Nutrient Cycles: Recycling in Ecosystems, The Carbon and Nitrogen Cycles

Edited by Jamie (ScienceAid Editor), Taylor (ScienceAid Editor), Sim, Jen Moreau and 3 others

Nutrients are chemicals necessary in any ecosystems for organisms to effectively grow, survive and decompose. A nutrient cycle is the perpetual movement of nutrients from the physical environment into a living organism and then recycled back into the physical environment. The health and stability of any ecosystems and the organisms that exist within it is highly dependent on a balanced and table nutrient cycle. Nutrient cycles involve both living and non-living contributors and include biological, environmental and chemical processes and interactions. The nutrients most utilized in ecosystems are non-mineral nutrients such as carbon, hydrogen, and oxygen. Macronutrients are also vital to ecosystems and include Nitrogen, Phosphorus, Potassium, Calcium, and Magnesium. The role of each nutrient in the cycle is dependent on the geology, the biological capabilities of the organisms, the chemical processes and reactions.

    Questions and Answers

    List and explain two different methods of sustainable agriculture?

    List and explain two different methods of sustainable agriculture. How does each method work why is each method beneficial for both agriculture and the environment?

    Sustainable agriculture is a method that uses unwanted organic products such as small wood pieces or chips, manure of animals (animal wastes), fruit and vegetable peels, that are usually thrown away, and incorporate them and turn them into fertilizers for crops, or pest repellents or for enriching the soil. It is a very useful method in saving money and at the same time producing a better quality of crops and higher quantity.

    • One method of sustainable agriculture can be the enrichment of soil. For example, when you bury manure of cows under piles of wood chips and leave them for a while, after some time, decomposers and worms decompose the wood chips along with the manure and turn them into a compost that is full of microorganisms. This compost can be used as fertilizer for crops. It is organic, cheap and at the same time it can improve the quality of soil and environment by producing more crops and at the same time not polluting the environment with pesticides and chemicals.
    • Another method can be pest management and control. For example, once you reintroduce the microbe that fights the diseases into the plant or the soil, then this plant or soil will be immune against the certain types of pests and microorganisms and as a result will not be affected by them. This method is very efficient because first, it eliminates the use of chemical fertilizers which are unhealthy for the consumers of these crops, and also very efficient in yielding higher quantity and better quality.
    • A third method can be rotation of crop. For example, planting different crops and rotating each year from one type of plant to the other, such as when you plant legumes the first year, these legumes enrich the soil with nutrients that can be used the following year to yield better crops of another type that consume these nutrients.

    Yes how does the nitrogen cycle help recycle nutrients?

    Nitrogen cycle recycling nutrients in the environment

    • Once inorganic nitrogen penetrates the soil (from the atmosphere), it is absorbed by a certain type of bacteria that are found in the nodules of leguminous plants.
    • These bacteria convert the inorganic nitrogen to an organic compound (such as protein, DNA, etc.)
    • The organic molecules are then released into the soil to be used by other plants, animals, and humans for survival and build up of other proteins.
    • When these organisms die, they will be degraded (with the help of the decomposers) and ammonia will be produced.
    • This ammonia will then be absorbed once again by the leguminous plants and the process will continue.
    • This is how nitrogen cycle will recycle nutrients.

    Nitrogen, Carbon and Phosphorus Cycles

    The carbon cycle deals with the interaction of carbon between living organisms and the nonliving environment. This cycle is a process through which all carbon rotates. The main result of the carbon cycle is to serve as a great natural "recycler" of carbon atoms.
    The cycle works in a very basic way. First, carbon is taken from carbon dioxide found in the air. Plants take in carbon dioxide from the atmosphere. Plants absorb carbon dioxide from the atmosphere and use it, combined with water they get from the soil, to make substances they need for growth. The carbon is then mixed with water. Carbon dioxide is then formed into sugar (glucose). The process of photosynthesis incorporates the carbon atoms…show more content…

    Carbon dioxide is very important in the atmosphere, however only in moderation. For centuries humans have been burning coal, oil, and fossil fuels therefore releasing tons of carbon into the air. The problem with this is that this can cause a problem known as global warming. This is a major climate problem, which has series results on people and the environment. The result on people can be very deadly. Too much carbon in the air can cause cancer.

    The nitrogen cycle is extremely important. This is because of the importance of nitrogen itself. Nitrogen is a basic element of life. It also makes up 78 percent of the Earth's atmosphere. It forms an essential part of amino acids (which make up proteins) and DNA. Nitrogen is essential for all living cells. The nitrogen cycle consists of 5 steps. First the basic element nitrogen in converted to ammonia. This process is called nitrogen fixation. This process is done by nitrogen fixing bacteria. Then the ammonia gets converted to nitrate. This process, called nitrification, is done by soil bacteria. Assimilation is the third step. Here the ammonia and the nitrate are absorbed by plants. Ammonification converts the nitrogen into ammonia. This process is done by ammonifying bacteria. The final step is denitrification. Here the nitrate is converted back to nitrogen. Denitrifying bacteria aid in this process.
    Like all other elements, nitrogen is very important in life but in moderation. We sometimes cause an overload
