✓
Answer
→ Ecosystem term is introduced by A. G. Tansly for the first time.
→ Ecosystem is a result of interaction between all living and non living factors of environment.
→ In an Ecosystem, all biotic and abiotic components are linked by unidirectional energy flow and nutrients cycle.
→ Biotic components : plants, animals, microbes.
→ Abiotic components : solar energy, water, air and land etc.
→ Types of ecosystem : Different types of ecosystems of nature, constitute the giant ecosystem-the biosphere. The ecosystems are categorised in to two as follows:
(1) Natural ecosystems :
→ They are operated by themselves under natural conditions without any major interference by man.
(2) Man-made ecosystems crop fields and aquarium.
Based upon the particular kind of habitat, these are further divided as :
(1) Terrestrial ecosystems : (a) forest (b) grassland (c) desert.
(ii) Aquatic ecosystems : They may be further divided as fresh water and marine water.
