CONCEPT OF ECOSYSTEM
This is the basic ___________ and ____________ unit of ECOLOGY.
ECOSYSTEM; STRUCTURAL; FUNCTIONAL
CONCEPT OF ECOSYSTEM
According to this source, ecosystems are basic units of nature on the face of the earth.
TANSLEY (1935)
CONCEPT OF ECOSYSTEM
According to this source, ecosystem is an ecological unit, or a subdivision of the landscape, or a geographic area that is relatively homogenous and reasonably distinct from the adjacent areas.
MAR (1961)
CONCEPT OF ECOSYSTEM
According to this source, ecosystem is the basic functional unit in ecology since it includes both organisms (biotic) & abiotic environment, each influencing the properties of each other and both necessary for the maintenance of life.
ODUM (1971)
CONCEPT OF ECOSYSTEM
According to Tansley (1935) ecosystems are _____ _____ of nature on the ______ of the earth.
BASIC UNITS; FACE
