Ecosystem | Source

Ecosystem is the environment where biotic/ living things live and interact with nonliving things/abiotic factors such as coral reef, forest, grassland, farm etc. In 1935, the word “ecosystem” was invented by a British ecologist Sir Arthur George Tansley, who depicted natural system in “constant interchange” among their biotic and abiotic parts.

Biotic parts such as plants, animals and bacteria etc.
Abiotic parts such as the soil, air, water etc.
Ecology is a branch of science that was developed by scientist to make the study easier about the relationship between biotic things and their physical environment which is the abiotic factors – and ecosystem is part of the concept of ecology in an organized view of nature.

Biosphere is the earth’s zone of air, water and soil that has the capability in supporting life. This zone reaches about 10 km into the atmosphere and down to the lowest ocean floor. In simpler term, the biosphere is the surface of the hierarchy on earth where living environment and organism thrive. It contains various categories of biotic communities known as biomes that is described by their overbearing vegetation such as deserts, tropical rainforest and grasslands. The biomes are in turn composed of various ecosystems.

Ecosystem has processes which sustain ecological balance:

The cyclic flow of materials from abiotic environment to the biosphere and then back to the abiotic environment.
Upholding the equilibrium of interaction inside food webs.
These processes must be maintained in the ecosystem; any interference with these cycles disrupts and affects ecological balance. Below are some of the reasons and causes of ecological imbalance in the living world.
