AAlexander Von Humboldt

BEugene Odum

CRachel Carson

DArthur G. Tansley

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.
