Adaptation is an evolutionary process where a plant or an animal becomes suited to living in a particular habitat. These are changes that take place over many generations through natural selection. Changes may be physical or behavioural.

Adaptations are special features that allow a plant or animal to live in a particular place or habitat. … These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another.

What is an adaptation in science?

In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. … Organisms can adapt to an environment in different ways. They can adapt biologically, meaning they alter body functions.

What are examples of plant adaptations?

The special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. Camouflage, as in a toad’s ability to blend in with its surroundings, is a common example of an adaptation. The spines on cycad leaves, keep animals from eating them.
