On average, sea turtles lay about 110 eggs in a clutch. however, only a fraction of the baby turtles make it to the ocean. then, an even smaller number have offspring of their own. while all zebras have stripes, no two zebras share the same stripe pattern. a lemur species called aye-ayes have very long, thin middle fingers that allow them to reach into holes in trees and dig out bugs to eat.

On average, sea turtles lay about 110 eggs in a clutch. However, only a fraction of the baby turtles make it to the ocean. Then, an even smaller number have offspring of their own. This is a case of overpopulation.

Overpopulation is a scenario when the organisms have more number of off springs than that can survive on the resources which are available for them. The competition for resources required for survival such as food and habitat results into overpopulation.

While all zebras have stripes, no two zebras share the same stripe pattern. This is a case of variation. Variation occurs when the individuals within a population show heritable variation in their traits. Variation takes place within different organisms of the same species which results into change in a population.

A lemur species called aye-ayes have very long, thin middle fingers that allow them to reach into holes in trees and dig out bugs to eat. This is a case of adaptation. Adaptation may be an inherited or a learned trait which increases the chance of survival of any organism in its environment. Adaptation may be behavioural or structural.
