Answer: A.) Heterotrophs compete for the same food source.
A food chain is a linear sequence in which food and energy is being transfered when one organism is fed the another organism in an ecosystem. A food web is a interconnection of two or more food chains. Heterotrophs are organisms which are dependent upon other organisms for the food requirement. In the given condition, the lizard and frogs are the heterotrophs which are dependent upon insects for their food requirement.
<em>Hence, heterotrophs compete for the same food source is the correct statement to describe the relationship between the lizard and the frog on the food web. </em>
