Answer:
D. Arthur G. Tansley
Read Explanation:
Correct Answer: Option D (Arthur G. Tansley)
The term "Ecosystem" was first introduced by Sir Arthur G. Tansley, a British botanist and ecologist, in 1935. In his paper published in the journal "Ecology," Tansley defined an ecosystem as a particular category of physical systems, consisting of organisms and inorganic components in a relatively stable equilibrium, open and of various sizes and kinds.
While the other scientists made significant contributions to ecology:
Alexander von Humboldt is known for his work on botanical geography and meteorology
Eugene Odum is famous for his pioneering work on ecosystem ecology, but did not coin the term
Rachel Carson is best known for her book "Silent Spring" which highlighted the environmental impacts of pesticides
Tansley's introduction of the ecosystem concept was revolutionary as it provided a framework for understanding the interactions between living organisms and their physical environment as a functional unit, which has become a fundamental concept in ecology and environmental science.
