Answer:There are 11 nonessential amino acids.
Explanation:amino acids are monomers of proteins.proteins are made up of carbon,hydrogen, oxygen and nitrogen.there are 20 amino acids found in proteins.

Answer:
Abiotic factors such as latitude and temperature can impact biotic aspects of food web structure like the number of species, the number of links, as well as the proportion of basal or top species. These biotics factors can in turn influence network-structural aspects like connectance, omnivory levels or trophic level. In this way, plants make, or produce, the beginnings of most of the food energy on Earth. This is why plants are called producers. They use some of the food energy to carry out their own functions, and store the rest of the energy in their leaves, stems, roots and other parts.
