How do autotrophs and heterotrophs benefit one another within an ecosystem?

A.
Autotrophs produce oxygen and carbon dioxide for heterotrophs, which produce chemical energy for autotrophs.
B.
Autotrophs transform chemical energy into radiant energy for heterotrophs, which fix carbon for autotrophs.
C.
Autotrophs fix carbon and produce oxygen for heterotrophs, which produce carbon dioxide for autotrophs.
D.
Autotrophs synthesize ATP and other nutrients for heterotrophs, which produce oxygen for autotrophs.

Apopulation of rabbits live in a local forest. some had a mutation for a large body and long legs. the graph below shows the number of both the mutant and the normal rabbits over 5 generations. which of the following statements is true for this scenario? question 7 options: the rabbits with the mutation were more successful with restricted food than the normal rabbits. both sets of rabbits were equally successful with the restricted food source. i the normal rabbits were more successful with restricted food than the rabbits with the mutation. the graph does not let us know which rabbit was more successful.
