The ecosystem and living organisms' cells have six primary elements: oxygen, hydrogen, carbon, nitrogen, phosphorus, and sulfur. The nutrient cycle, or the biogeochemical cycle, is the movement of these nutrients from the environment into plants, animals, and humans and recycling it again.
The primary elements mentioned earlier move through the earth’s ecosystem—atmosphere, water bodies, soil, and living organisms. It recycles and reuses these elements to maintain order. These nutrients fuel life, recycling themselves in a closed loop.
Nutrient cycles occur through living and nonliving organisms using chemical, biological, and geological processes. However, soil microbes are an essential element that helps foster nutrient cycles. Soil and its microbes help break down organic matter and release nutrients into a processing cycle, changing forms until they return to their original state.

Carbon is one of the most critical elements in the physical environment. It is essential to all life forms because they cannot survive without converting carbon dioxide in the atmosphere to carbon-based organic molecules of living organisms.
The carbon cycle recycles carbon at varying rates in different areas of the environment. It involves long-term carbon cycling through geologic processes and rapid carbon exchange among organisms in the earth’s atmosphere, surface, and crust.
This nutrient cycling occurs everywhere because carbon is stored in inorganic mineral nutrients in crustal rocks, the oceans, and the atmosphere. Carbon dioxide cycles faster between the atmosphere and organisms. Using photosynthesis, plants and marine organisms convert carbon dioxide into organic carbon.
This conversion helps them produce other organic molecules like starch, lipids, and proteins, which are necessary for the survival of animals and other living organisms that feed on them. Then, they break down the organic molecules in aerobic cellular respiration, which consumes oxygen and releases energy, water, and carbon dioxide.
The carbon dioxide released from the process returns to the atmosphere, where the cycle repeats itself. Carbon also recycles itself by decomposing living organisms and other organic matter.
The decomposition process involves bacteria and fungi breaking down complex organic compounds. The bacteria and fungi then release carbon dioxide back into the atmosphere. Photosynthesis and cellular respiration go hand in hand in cycling carbon. Besides burning fossil fuels, these are the only ways to process CO2 and return it to the atmosphere. So, a significant change in any of these processes influences the amount of carbon in the air.
The nitrogen cycle is crucial to the survival of living beings and organisms. Nitrogen is necessary for healthy plant growth and seed development. About 78% of the gas in the air is nitrogen. Still, atmospheric nitrogen is not helpful to organisms in its gaseous form. It becomes useful when nitrogen-fixing bacteria transform it.
There are various steps in the nitrogen cycle. These steps are:
Nitrogen fixation
Nitrogen assimilation
Ammonification
Nitrification
Denitrification
Nitrogen fixation is the process of converting atmospheric nitrogen into ammonia. Ammonia then becomes ammonium, which enters the soil and water reservoirs. The two types of nitrogen-fixing bacteria are non-symbiotic bacteria and symbiotic bacteria. The non-symbiotic bacteria are cyanobacteria, nostoc, and azotobacter. In contrast, the mutualistic bacteria include rhizobium, a bacteria common to leguminous plants.
The bacteria enter the root hairs of host plants, multiply, and influence the formation of root nodules. They enlarge plant cells and bacteria in close association. They convert atmospheric nitrogen to ammonia, which the plant uses for development.
Nitrates and ammonia from nitrogen fixation assimilate into tissue compounds of algae and higher plants, which animals eat. After assimilation, the animals convert them to the mineral nutrients they need. Ammonification begins by decomposing living organisms and their waste products.
Depending on the soil conditions, the ammonia produced can leave the soil or be changed into other nitrogen compounds. Nitrification is converting ammonia in soil into nitrates by nitrifying bacteria. At the same time, denitrification is the process of denitrifying bacteria and metabolizing bacteria.
The denitrifying bacteria is more active in water-logged areas. It breaks down nitrates in the soils, converting them to atmospheric nitrogen. The nitrogen cycle is a never-ending process of nitrogen conversion that sustains life and the food chain.

It’s an edible vegetable oil that comes from the fruit of oil palm trees, the scientific name is Elaeis guineensis. Two types of oil can be produced; crude palm oil comes from squeezing the fleshy fruit, and palm kernel oil which comes from crushing the kernel, or the stone in the middle of the fruit. Oil palm trees are native to Africa but were brought to South-East Asia just over 100 years ago as an ornamental tree crop. Now, Indonesia and Malaysia make up over 85% of global supply but there are 42 other countries that also produce palm oil.
Palm oil can be produced more sustainably and there is a role for companies, governments, and consumers to play. The Roundtable on Sustainable Palm Oil or RSPO was formed in 2004 in response to increasing concerns about the impacts palm oil was having on the environment and on society. The RSPO has production standards for growers that set best practices for producing and sourcing palm oil, and it has the buy-in of most of the global industry. RSPO encourage companies to:
Set robust policies to remove deforestation, conversion of other natural ecosystems, such as peatlands, and human rights abuses from their supply chains
Buy and use RSPO certified palm oil across their operations globally
Be transparent in their use and sourcing of palm oil ensuring they know who they are buying from and where it’s been produced
It is important that the palm oil industry continues to invest in and grow support for and smallholder programmes and sustainable landscape initiatives. WWF is also working with governments in both palm oil using and palm oil producing countries to make sure that national laws are in place to ensure that any palm oil traded is free of deforestation, conversion and exploitation.

Imagining a situation where cutting down trees could be deemed sustainable may be difficult. Leaving forests untouched would seem more acceptable, but in the face of human dependency on forest resources, sustainable forestry is the best course of action.
Sustainable forestry is all about balancing our needs and the well-being of forest ecosystems. The forest management method seeks to mimic how natural forests operate.
Wild forests are a hotbed of eco-diversity and great carbon sinks. They often have economic and cultural significance to local communities. Sustainable forestry aims to cultivate forests that can provide the same social and environmental benefits without giving up on the economic benefits.
Simply defined, sustainable forestry is cultivating trees for timber while protecting the surrounding biological and social ecosystem.
It's important to note that no universal sustainable forestry management system exists. That's because forest ecosystems and their social environment differ from place to place.
Moths are winged flying insects. They are a paraphyletic group of insects that consists of all members of the order Lepidoptera, excluding butterflies.
Lepidoptera, which translates to “scaly-winged,” is an order of insects whereby insects undergo a larval stage popularly known as a caterpillar, a pupal stage known as chrysalis, or cocoon, and the adult stage known as butterfly or moth. Many people often confuse moths with butterflies, but they differ from each other.
There are about 160,000 unique species of the nocturnal flying moth1, except for a few species active during the day, like the sphinx moth, day moth, and buck moth. On the other hand, moths’ close relative, the butterfly, has 17,500 species. There are nearly 11,000 species of moth in the United States and 2,500 in the United Kingdom.
Like all insects, moths have six legs, two antennae, a head, a thorax, and an abdomen. They have a life span of six months to three years. Furthermore, moths range in size from a few millimeters to the largest moth species with a wingspan of 10 inches (25cm).
In addition, moths are diverse in their ecology. Moths inhabit places like farmlands, gardens, woodlands, marshlands, sand dunes, and even mountains. They also tend to lay eggs within cracks, near plumbing fixtures, and other dark areas. Moths come in various types, from the familiar brown house moth to multicolored, unique ones.
Plants that flower, especially native varieties, should be easy for you to get your hands on. Simply ask for those grown in your particular region. Native flowering plants won’t be difficult to grow either at your location because of their suitability to the local climatic and geographical conditions.
Honey bees love a variety of flower species because they are flat, open, and tubular in structure. Therefore, The flower shapes make it easy for bees to enter and ensure that pollen brushes on their bodies. They also have bright colors and exotic scents, which are particularly appealing to the honey bee. They love purple, blue, and yellow flowers the most.
It won’t be difficult to find or grow flowering plant species because they can thrive in most living conditions. You can check out the local nursery to see what varieties are available. A website such as Native Plant Finder could be a useful guide in figuring out which flowering plants native to your region perfect for attracting pollinators.
Great options for some of the best flowers that attract bees include:
The major challenge in eliminating monoculture is keeping the food supply high enough so people don't go hungry. That is a valid concern, as food insecurity, which discriminately affects low-income households, would only worsen if the supply suddenly dipped.
Another challenge is that many local farmers struggle to transition from monocropping. They may face complex financial or technical issues.
Political willingness is also a concern, as the government can institute policies that support sustainable farming. They also have the authority to compel large agro companies to adopt more environment-friendly practices.
However, monoculture is not sustainable. Past trends show that continuing monocultural farming would only increase nitrogen pollution, irrigated fields, and agricultural encroachment.
Conclusion
Many farmers have turned to monoculture to avoid lower yields. Despite its seemingly great economic benefits, monoculture has unpleasant environmental consequences. Diversity in agriculture is the way to go. It has long-term positive effects on the environment and the economy.
Ocean acidification results from a chemical reaction caused by the absorption of carbon dioxide from the atmosphere. Many human activities, such as burning fossil fuels, various land uses, and manufacturing practices, release tons of C02 into the atmosphere. These carbon emissions don’t stay in the atmosphere.
Plants and the oceans absorb carbon dioxide. The world’s oceans absorb 30% of the carbon dioxide in the atmosphere, causing an increase in ocean acidity. An increase in the ocean’s pH directly impacts excess carbon pollution from burning fossil fuels. The ocean absorbs one-third of the carbon released from burning fossil fuels.
The pH scale is from 0 to 14; anything over 7 is alkaline, and anything below 7 is acidic. More hydrogen ions lead to higher acidity and a lower pH. As seawater absorbs carbon dioxide, it forms carbonic acid (H2CO3). Carbonic acid (H2CO3) is a weak acid that separates into hydrogen ions and bicarbonate ions, increasing its acidity.
Before the industrial revolution began, seawater's pH was 8.2. In the 21st century, it dropped by 0.1 pH units to 8.1. Scientists predict surface ocean waters will become more acidic by 21002, falling to 7.8. 7.8 makes the ocean 150 times more acidic.
