Students create food chains to learn how energy flows through an ecosystem. After completing several chains, students notice some of the same animals appear on several food chains. The students conclude that within an ecosystem, food chains combine to create food webs. Do the students reach a logical conclusion?

Yes, the students can be said to have reached a logical conclusion.

Explanation:

The food chains that are existent in the environment are not clearly separated from each other. This is because many top predators are common to several food chains. These predators eat many other animals from multiple species that form the second block of the energy cycle pyramid. Thus, the intermingling of these food chains results in the formation of food webs that are bigger and more complicated.
