ECOSYSTEMS

Ecosystem comes from the Greek word oikos which means home and systema or

system.

Ecosystems are made up of both living and non-living things

.Parts of an ecosystem that are living or were once living are called biotic.

Parts of an ecosystem that are non-living are called abiotic.

An ecosystem is the interaction between these living (biotic) and non-living (abiotic) factors.

There are ecosystems everywhere…big and small
