Answer;
-Predator-prey relationship
Step-by-step explanation;
-Predator-prey relationship is an interaction between two organisms of unlike species in which one of them acts as predator that captures and feeds on the other organism that serves as the prey.
-A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
-Predation acts as a mechanism of population control in an ecosystem. Therefore, when the number of predators is scarce the number of preys should rise. When this happens the predators would be able to reproduce more and possibly change their hunting habits. As the number of predators rises, the number of preys decline. This results in food scarcity for predators that can eventually lead to the death of many predators.
