If the population of rabbits in this ecosystem decreased dramatically because of certain environmental changes, which organisms' food supply would decrease? A. Owl and snake B. Jackal and wildcat C. Green plant and mouse D. Goat and wildcat

Answer: B. Jackal and wildcat

Explanation:

In a food chain the food and energy are distributed among the ecosystem when one organism is consumed by the other. The rabbits are the primary consumers which consumes plants and their products. These can be consumed by the secondary and tertiary consumers. The jackal and wildcat are the secondary consumers. These have bigger jaw and appetite that they can consume the entire rabbit and also they may hunt for the number of rabbits in the population. But the owl and snake cannot consume the entire rabbit instead they can just feed upon their remaining parts as they have small jaw and small appetite.
