• B. Ernst Haeckel
• C. Darwin
• D. Allen

Answer 1

The correct option is A Sir Arthur Tansely

Ecosystem refers to a self-regulated and self-sustaining structural and functional unit of nature. It consists of living beings and their physical environment. The term ecosystem was coined by Sir Arthur Tansely.

Ecology is a branch of biology that deals with the study of interactions between organisms and their environment. The term Ecology was introduced by Ernst Haeckel.

Darwin proposed the theory of natural selection. Natural selection is the process through which nature selects and favours the survival of only those organisms in a population who are better adapted to a changing environment and can give birth to healthy and fertile offspring.

Allen proposed Allen's rule which states that mammals living in colder regions generally have shorter ears and limbs to minimise heat loss compared to the animals of the same species living in warm areas.
