Lesson details
Key learning points
- Cold environment ecosystems exhibit interdependence of climate, water, soils, plants, animals and people.
- Food chains and food webs show how biotic and abiotic components are interdependent in a cold environment.
- Nutrient cycles show how biotic and abiotic components are interdependent in a cold environment.
Keywords
Biotic - the living elements of an ecosystem (e.g. plants, animals)
Abiotic - the non-living elements of an ecosystem (e.g. water, nutrients)
Interdependence - the connections between different components of the environment, where each component depends on or influences the others
Evapotranspiration - the transfer of water to the atmosphere through evaporation from surfaces and transpiration from plants
Common misconception
Soil is a biotic component of ecosystems because it contains living organisms.
Soil is classed as an abiotic component because soil itself is non-living.
