Lesson details
Key learning points
- Hot desert 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 hot desert.
- Nutrient cycles show how biotic and abiotic components are interdependent in hot desert.
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
Litter in the nutrient cycle is considered biotic.
Litter in the nutrient cycle is considered abiotic because it consists of non-living organic material, such as dead leaves and decomposing matter. Although it originated from living organisms, once it becomes litter, it is classified as non-living.
