the size of a food chain can vary, but the number of levels that a food chain can reach is limited. why does this limit exist?\nplants are not infinite in number.\nproducers are limited by consumers.\ncarnivores are too large to be eaten.\nenergy is lost at each trophic level.

Answer

Brief Explanations:

In a food - chain, energy transfer between trophic levels is not 100% efficient. As energy is lost at each level (about 90% is lost as heat and other forms), there is not enough energy to support a large number of levels.

Answer:

Energy is lost at each trophic level.
