Question

7. A predator’s ability to find prey can often be complicated by behavior of the prey. How can the prey make it difficult for the predator to locate the prey?

8. The social interaction of animals sometimes influences food finding. Describe how this can work.

Answer 1

7. The prey make difficult for the predator them by the following phenomenon:

A. The first line of defense is to avoid being detected by the predator by means of reducing noise production and any visual cues that the predator might use to locate the prey. Frogs and crickets usually stop singing as another creature approaches so that predators cannot detect them.  

B. Some other prey have evolved camouflage coloration that blends into the background making it difficult for visual predators to find them. Many moths camouflage them and look like the bark of trees on which they rest during the day so that bird cannot detect them and also Predators often use prey movements to detect them, so many prey remain as still as possible when a predator approaches.

8. Animal social interaction may provide individuals with increased access to food by means of information sharing and cooperative defense against non-group members and the other way to find food by means of animal social interaction is nesting near other individuals and forming colonies causes information sharing and increased ability to exploit a highly variable insect food resource. Once colonies were formed, it increases incidence of food stealing so they do not need to travel greater distances for food searching.
