Predator-prey relationship is the interaction between two species in which one of them acts as the predator and preys on the other. The populations usually fluctuate, like the graph shown.
Example 1 : Tarantula and Tarantula Hawk
Example 2: Desert Coyote and Pocket Mouse
The Desert Coyote needs food, so it will kill the mouse for
food. The coyote is the predator and the mouse is the prey. The mouse
has ways of fighting back, though. It's called adaptations. Adaptations
are when a species evolves to stay alive. The Pocket Mouse has evolved
to be faster, and more cunning. The coyote has evolved to be more silent
and faster.
