Which of the following is an example of a disadvantage that animals face when they live together in groups? a. They must compete for food and mates. b. They are difficult for predators to find. c. They are especially protected from disease. d. They cannot spot predators quickly.

A).

Explanation:

It is shown in many shows about nature, that going in a group has its advantages of protection, but when it comes to hunting / eating and mating season, it is incredibly challenging and can lead to fights that result in death.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
