All organisms have adaptations. An adaptation is an inherited trait that helps an organism survive in its environment. Without adaptations, organisms would not be able to change along with the environment they live in.

null

An adaptation causing these bugs to look like sticks keeps them safe from predators.

Organisms with advantageous adaptations are more likely to live longer and pass these traits on to their children. This causes more organisms in the next generation to have this adaptation.

null

Blowfish that had the ability to puff up and scare away predators lived longer than other blowfish and passed this trait on to their young. The ability to puff up is an adaptation because it is an inherited trait that helps the blowfish survive in its environment.

Some animals, such as this bull, are given drugs to make them grow more muscle. The offspring of animals given these drugs do not get this trait. Is this extra muscle an adaptation?

Yes, it is an adaptation because the muscle helps the animal survive in its environment.

No, it is not an adaptation because the animal cannot pass the trait on to its offspring.

Check for Understanding:

1. An adaptation is an inherited trait that helps an organism survive in its environment.

2. Adaptations help organisms live longer.

3. Adaptations can become more common as they are passed on to offspring.

There are two types of adaptations: physical adaptations and behavioral adaptations. Physical adaptations, also known as structural adaptations, are inherited changes to an organism's body parts. Physical adaptations can occur in external or internal body parts.

null

This butterfly's long tongue, called a proboscis, is a physical adaptation because it is an adaptation to a body part.

Behavioral adaptations are inherited behaviors that help an organism survive in its environment.

null

This masked weaver is born knowing how to build its nest. This knowledge is an example of a behavioral adaptation.

Some animals, like poison dart frogs, are born with bright colors to warn predators that they are poisonous. What kind of adaptation is this?

It is a physical adaptation because frogs get the color by eating blue fruit.

It is a physical adaptation because it affects the frogs' appearance and can be inherited.

The blue color is not an adaptation.

It is a behavioral adaptation because frogs show off the colors by jumping.

What is a behavioral adaptation?

a change in an organism's behavior that is not inherited by its offspring

any behavioral trait

a behavior that an organism learns during its life

an inherited behavior that helps an organism survive in its environment

12.

Imagine a fish is born with the ability to swim faster than its main predators. Is this an adaptation?

yes, and it doesn't matter if it can pass the trait on

no, because it does not help the fish survive

yes, if it can pass the trait on to its offspring

no, because it is a behavioral trait
