Who called the ecosystem as the basic functional unit of ecology?

1 Introduction. Tansley (1935) coined the term “ecosystem” to recognize the integration of the biotic community and its physical environment as a fundamental unit of ecology, within a hierarchy of physical systems that span the range from atom to universe.

Why is ecosystem The basic functional unit of ecology?

Explanation: The ecosystem is defined as a functional unit of ecology because it is the smallest unit of nature, which is independent and self-sustaining due to various interactions between abiotic and biotic components and different organisms among themselves.

Which is the basic functional unit of ecology?

Answer: The correct answer is A) Organism.

Thus, it includes all the life forms and their surroundings ( biotic and abiotic components). Organism is considered as the functional unit of ecology.

Who defined ecosystem as the structural and functional unit of ecology?

Hint: The name of the structural and functional unit of the environment was given by A.G Tansley. Complete answer: The structural and functional unit of the environment is the ecosystem. The ecosystem consists of biotic and abiotic factors and shows interactions among themselves.

Who gave the name ecosystem?

The term “ecosystem” was first used in 1935 in a publication by British ecologist Arthur Tansley. The term was coined by Arthur Roy Clapham, who came up with the word at Tansley’s request. Tansley devised the concept to draw attention to the importance of transfers of materials between organisms and their environment.

Is ecosystem a functional unit of ecology?

Note : The ecosystem is defined as a functional unit of ecology because it is the smallest unit of nature, which is independent and self-sustaining due to various interactions between abiotic and biotic components and different organisms among themselves.

Why ecosystem is structural and functional unit of ecology?

The ecosystem is the structural and functional unit of ecology where the living organisms interact with each other and the surrounding environment. In other words, an ecosystem is a chain of interaction between organisms and their environment.

What are the main functional ecosystem units?

Thus, in any ecosystem we have the following functional components: (i) Inorganic constituents (air, water and mineral salts) (ii) Organisms (plants, animals and microbes), and (iii) Energy input which enters from outside (the sun). These three interact and form an environmental system.
