4.1 Ecosystems



An ecosystem is a community of organisms in a particular habitat.

The study of habitat is non biological (abiotic factors) eg:
-Cycle of daylight/dark (photo period)
-Temperature (local/seasonal/annual)
-Rainfall
-Humidity
-Slope of the land

The community is made up of populations of different species and their interacting with each other. Population is the number of individuals of a particular species. Species are organisms that reproduce to give fertile offspring. The main type of interacting is: Feeding.

Summarise:
Ecosystem-community of organisms in a particular habitat-community of different species interacting.
