Question

60sec essay on “Ecosystem for
Sustainable living”

Answer 1

Answer:

‘Eco’ means natural habitat. The system for the existence of natural habitat

of biological community (of organisms) interacting with their physical

environments is the ecosystem. It includes all the living things (plants, animals,

and organisms) in a given area that interact with each other, as well as with the

non-living entities (weather, earth, sun, soil, climate, atmosphere, land) around

them. The living and non-living (i.e. physical) components are linked together

through nutrient cycles and energy flows. All the plants and animals (both macro

and micro) on the Earth rely on the respective ecosystems for food and

habitation. Therefore, the ecosystems must maintain a delicate balance in

order to stay vital. Human beings like other organism, also rely on ecosystems

to have food and natural resources. Depending on various characteristics, the

eco-system has been classified primarily as Terrestrial and Aquatic; but thereare many sub-groups as shown in Box – I & II. It is to be understood, when

natural resources are harvested out of an ecosystem, it can disrupt the

delicate balance if not done in a rational and responsible way. Nevertheless,

following diagram (Fig.1.1) shows the different components of ecosystem.
