Energy and matter cycle through the ecosystem on the Atlantic coast. Describe one limitation and one benefit of using a food chain as a model to show these processes. (What is one good thing about a food chain and what is one bad thing)

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
