Unit Summary
This unit teaches pupils about the location, characterisitics, opprtunities and challenges associated with one global environment, either hot deserts or cold environments. Pupils will also learn about plant and animal adaptation and about issues facing their chosen environment.
Lesson Summary
You will learn to explain how biotic and abiotic components in a hot desert such as soil, climate, animals, plants and people are interdependent.
Key Notes
- 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.
Vocabulary To Learn
- 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 Mistakes To Avoid
- Litter in the nutrient cycle is considered biotic.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key 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.
2. Define this geography term and use it in an example. 'biotic'
the living elements of an ecosystem (e.g. plants, animals).
3. Correct this common geography misunderstanding.
Mistake: Litter in the nutrient cycle is considered biotic. Correction: 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.
