Question

'Adjustment to the environment' is called as
A. Adaptation
B. Mimicry
C. Hibernation
D. Aestivation

Answer 1

For survival, every organism needs to adjust to the changing environment. Adjusting in the adverse surrounding environment is an evolutionary process. The process of adjusting to the environment is called adaptation.

Complete step by step answer: Adaptation is defined as changes acquired that may be physical or behavioural, which will help an organism to survive better in the environment. Every organism is well adapted to its own habitat. This is because every organism has developed special features may be physical or some behavioural characters that help them to survive. This development occurs because of the evolution of an organism. Evolution may occur because of gene mutation. Hence, Adaptation is a permanent process. Genes that are mutated are passed onto the next generation. Mimicry is a biological interaction where two organisms of different species resemble. The purpose of performing mimicry is to protect them from predation. One who acts is called Mimic and one whose acting is done is called a model. Hibernation is called winter sleep. It is the state where the organism undergoes dormant state. It is a state of metabolic depression in endotherms. Aestivation is also called summer sleep. This phenomenon is similar to that of hibernation, but the only difference is that it occurs in the summer months.
So, from the above information answer to the given question is option A.

Note: Acclimatization is different from adaptation. Acclimatization is reversible but adaptations are permanent. Acclimatization is a temporary change acquired by an organism. Acclimatization occurs only for a short duration of time.
