Question

What are behavioral responses or adaptations? Give one example.

Answer 1

Bhavioral Adaptation

All organisms have adaptations that help them survive and thrive.

Behavioral adaptations are the things organisms do to survive.

EXPLANATION

A bird species. One day a bird is born with a beak that is longer than the beak of other birds in the species.

The longer beak helps the bird catch more food.

Because the bird can catch more food, it is healthier than the other birds, lives longer and breeds more.

The bird passes the gene for a longer beak on to its offspring.

They also live longer and have more offspring and the gene continues to be inherited generation after generation.

Eventually the longer beak can be found in all of the species.

This doesn't happen overnight. It takes thousands of years for a mutation to be found in an entire species.

Over time, animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.

The characteristics that help a species survive in an environment are passed on to future generations. Those characteristics that don't help the species survive slowly disappear.

EXAMPLE : The breeding populations of Siberian crane occur in Arctic tundra of western and eastern Russia. The eastern populations migrate to China in winter. The western populations winter in Iran and India. However the last wintering population in India was recorded in the year 2002. Probably this particular group had become extinct.
