Question

what do the arrows in the food chain indicate about the flow of energy in an ecosystem?
raccoon
frog
grasshopper
grass
energy is continuously recycled by the organisms in an ecosystem.
more of the available energy in an ecosystem is given to large animals than to small animals.
organisms at the end of the food chain receive more energy than those at the beginning.
energy flows in one direction in an ecosystem, from producers to consumers.

Explanation:

In a food - chain, arrows represent the direction of energy flow. Energy starts from producers (like grass) and moves to consumers (grasshopper, frog, raccoon). Energy does not recycle in the same sense as matter in an ecosystem. Also, energy decreases as it moves up the food - chain, so organisms at the end receive less energy than those at the beginning, and there is no relation to the size of the animal in terms of the amount of available energy given in the food - chain concept.

Answer:

Energy flows in one direction in an ecosystem, from producers to consumers.
