Abiologist is studying a food chain in an ecosystem. in the food chain, wolves eat foxes, the foxes
eat rabbits, and the rabbits eat grasses.
which group of organisms is on the trophic level that holds the least amount of energy?
the wolves
the grasses
the foxes
the rabbits

the wolves

Explanation:

Before answering this question we must understand that the main source of energy comes from the sun. Photosynthetic organisms, such as plants and algae, transform this solar energy into chemical energy, using it to synthesize organic matter through the photosynthesis process. These organisms are called autotrophic (produce their own food). Within a food chain these organisms represent the trophic level that contains the largest amount of energy that will be passed to the next trophic level which is a herbivore animal that will feed on these plants. The animal that feeds on the herbal animal will receive less energy and the animal that feeds on it will receive much less energy and so on.

Thus we can conclude that in the food chain shown in the question above, the trophy that will receive the least energy is the wolves.
