Question

Who coined the term ecosystem?
A. Tansley
B. Odum
C. Warming
D. Darwin

Answer 1

Hint: The living organisms and the non-living matters interact together and are dependent on each other. The ecosystem is the group of organisms that live together in a particular area and interacts with the abiotic system of the environment.

Complete answer:
The ecosystem can be described as a community of biotic and abiotic elements of an environment and both these components interact together to sustain each other. The abiotic and biotic components are linked together through the various energy and nutrient cycles.
The term ecosystem was used for the first time by Arthur Tansley in 1935. Tansley through his works devised the concept of importance of transfer of materials that takes place between the organisms and their surroundings. According to him, the term ecosystem describes not only the organism complex but it also includes the whole complex of physical factors. The ecosystem are not merely as natural units but they were regarded as mental isolates by Tansley.
Tansley coined the word ecosystem and elaborately described the relation between the biotic and abiotic systems as an interacting system that was established between groups of living creatures or organisms and their environment in which they reside and live. The word ecosystem was first of all published in a highly influential paper in which Tansley clarified the key terms and discussed further the concepts in ecology.
The concept of ecosystem by Tansley was later on adopted by various scientists and workers such as E.P. Odum, Lindeman.
Odum is considered as the father of modern ecology due to his various pioneer works in ecology. Warming was the author of the important book on ecology named as Oecology of Plants.

Therefore, the correct option is option A.

Additional information:
The term ecosystem described the various types of complex relationships and associations between the abiotic and biotic components of an environment. The abiotic components include the physical and chemical environment that are nonliving units but regulate the growth and distribution of the other components which are the biological components. The living organisms are included as the biotic components.

Note: The term ecosystem was coined by Arthur Tansley when it was first of all published in a publication that described his ideas about different types of system that operated between the two important components of the environment which are abiotic and biotic components.
