The data showed that recently the alligator population has decreased. How could the decrease in the alligator population affect the other populations? Be sure to explain whether the gar population, the diving duck population, and
the crab population will change, and why.

the gar population will increase, the diving duck will decrease slightly and the crab population will decrease

Explanation:

Since the alligator population will decrease, the gar population won't have anything to limit their population, so they will increase fast. The crab population will decrease fast as there are more gars to eat them. The duck population will decrease slightly as the gar is eating more crabs then the duck

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.
