Hint: The Scientist is a Phytologist, he is also from the British Ecological Society, and gave the Ecosystem concept. Also being Awarded Linnean Medal Fellow of the Royal Society. He was an English botanist.

Complete answer:
The Scientist who coined the term “ecosystem” and also recognized the integration of the biotic community and its physical environment as a fundamental unit of ecology. The Scientist is A G. Tansley.
The ecosystem stem is an essential component of the biosphere. It consists of a community of biotic(living beings) and the abiotic or physical environment both interacting with each other. Word ecosystem was coined by Tansley in 1935 but previously the term 'biocoenosis' was used.

Additional information: E. Haeckel coined many words commonly used by biologists, such as phylum, phylogeny, and ecology.
The bioticotic structure is defined as the way organisms interact within an ecosystem. Every organism in a species has a tolerance level, optimum range, and zone of stress for the abiotic factors present in the environment; these anabioticicoticic factors are a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, for example, temperature, water, and light. In a marine ecosystem, abiotic factors would include salinity and ocean currents. Ecosystems can be simplified into three basic groups of organisms: producers, consumers, and decomposers.
But no doubt, Abiotic and biotic factors work together to create a unique ecosystem.
So, the correct answer is, ‘(b) A.G. Tansley’.

Note: Ecosystem is categorized into natural and artificial ecosystems. Natural ecosystem included forest, desert, and grassland. Artificial ecosystems are ponds, lakes, rivers, marine, estuaries.
