Question

What do you understand by adaptations in organisms and why do they adapt?

Answer 1

Hint:In order to increase their chances of survival in that environment, adaptation is the modification of the individual to their environment.

Complete answer:
Adaptation is the state of adaptation: the degree to which an organism in a given set of environments can survive and reproduce.
The theory of adaptation, also known as the theory of survival or the survival of the fittest, is the capacity of an organism to adapt to changes in its environment and adjust overtime accordingly. Adaptations occur over generations of a species and these characteristics are passed on from generation to generation until the entire species evolve to be better suited to its climate.
Charles Darwin Adaptation Theory, the most prominent scientist associated with adaptive theory, suggested three changes as habitat changes.
Habitat tracking is when a species changes its habitat or finds another area close to the one in which it previously lived. The effect is the species dying out or becoming extinct when a species is unable to move or change.
Genetic manipulation is when natural selection causes the species to have an advantage over the rest of the population with small mutations, providing them with the best access to food and mates.
Typically, one of three types of changes are seen: systemic, physiological, or behavioral.
It is also evident from the above discussion that species adapt in order to survive in critical circumstances.

Note: Species share basic needs which are met by adaptations. They need to defend themselves, obtain resources, replicate and protect themselves against the weather from enemies. What differs is the way this is achieved by each organism.
