Answer:
A. Nitrogen is the most abundant
.
B. Oxygen is the most plentiful gas about 21% by volume.
Explanation:
Nitrogen is the most abundant gas present in the atmosphere about 78 % by volume while the second most abundant gas is oxygen which is about 21 % in the atmosphere which is used by the living organism for breathing and energy production. Nitrogen is used by the plants for the production of amino acids and enzymes formation. Carbon-dioxide is present in a very low amount about 0.03 % in the atmosphere which is used by the plants during photosynthesis process.
Answer:
Epistasis
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants
In Genetics, a gene pair has the ability to influence other gene pairs based on their combined activities which produces some effect on phenotype; this is called epistasis.
If an ecosystem lost its producers, there would be no way for energy to move up the web and the ecosystem would most likely fail. Without these energy-capturing organisms, herbivores would get no energy or food. Without them, carnivores would get nothing as well. Because decomposers get energy from all three, they would also die out.
If only decomposers were removed, there would be a lack of nutrients in the soil for plants. This would result in the above (loss of energy, food, and other commodities).
