1.	(a) Define an ecosystem. Give examples of any two ecosystems.(b) List the biotic and abiotic components of an ecosystem.
Answer» (a) An eco system is a self contained unit of living things(plants, animals and decomposers), and their non living environment (soil, air and water). Example – a grassland and a forest. (b) 1. Biotic component – The biotic components of the ecosystem is a community of organisms which is made up of many different inter-dependent populations. It includes – producers, consumers and decomposers. 2. Abiotic components – The abiotic components of the ecosystem (non living components) include the physical environment like soil, water and air alongwith the in organic substances like carbon dioxide, nitrogen, water and phosphorous.
