5)What is the relationship between a predator and a prey? Two predators with the same prey?
A predator is an organisms that feeds on other organisms which is the prey
In the picture above, the spider is the predator while the fly is the prey.
An increase in population of prey would means more food for the predator, thus causing the population of predator to increase. However, this causes the population of prey to decrease, which in turn results in a decrease in the predator population due to the lack of food. As the population of predatore decreases, the population of prey would increase again and so on..
A prey-predator graph
If they are two predators feeding on the same prey. Both predators will be competing against each other for food. This causes the population of prey to decrease. Overtime both population of predator would decrease if they do not look for other scoure of food and the population of prey would increase when there are lesser predators.
