Concept:Adaptation is the adjustment of an organism to its environment through changes in structure, physiology, and behaviour.
Explanation:Adaptation helps plants and animals survive in their natural habitats.
These modifications can be structural, such as changes in body parts or shape.
They can also be physiological, like internal functions that help the organism cope with conditions.
Behavioural modifications include actions or patterns that improve survival and reproduction.
Evolution explains changes in living things over long periods, not just individual modification.
Variation refers to differences among individuals or groups of the same species.
Succession describes how the structure of a biological community changes over time.
Therefore, the correct term for modification in structure, physiology, and behaviour is adaptation.
