Explain why echolocation is a superior adaptation for insectivorous bats rather than fruit bats.

Because insectivorous bats need this particular feature in order to detect and spot insects that are within their vicinity or elsewhere with ease. Unlike fruit bats that have less scarcity when it comes to food, these insectivorous bats need to seek out insects in order to feed.

Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time.
