What is Adaptation?

Generally, organisms develop features that enable them to live (adapt) successfully and reproduce in a particular environment.  These features may be as a result of changes in structure, functions or behaviors for the purpose of survival in an environment.

Definition of Adaptation

Adaptation is simply defined as the ability of an organism to survive in an environment due to its structural, functional and behavioral changes that enables it to live successfully in that particular environment or habitat


The two most contrasting environment are the aquatic and terrestrial environment. Organisms living in each of these environment must show adaptation features suited for their particular environment. These adaptive features are determined by
1. Nature of medium of gaseous exchange ( that is water or air)
2. Osmoregulation and water loss
3 Ability to move about within the environment

Adaptation of plants to Aquatic and Terrestrial environment 

Availability of water through rainfall is the main environmental factor that is responsible for the major biomes of the world. This is because plants (producers) are greatly affected by the availability of water and show various adaptations that are related to the amount of water in their environment.
