Cell, tissue, organ and organ system
Based on the graph, you can see that the population of grass is high, which indicates that the one that feeds on them has been affected. Logically, the rabbits are those that feed on it and as you can see, their population has lowered, and so did the snakes and the hawk.

Answer:
A
Explanation:
Organisms on Earth use nitrogen to build proteins necessary for cell
development.
The nucleus stores genetic information
Answer:
Excess nitrogen can cause over-stimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters. So few organisms live in these conditions or even can suffocate and die.
