6Unit 1 Diversity of Living Things
Types of diversity:
- Genetic diversity.
- Species diversity.
- Ecosystem diversity. How biodiversity supports ecosystem stability:
- Genetic diversity results in a greater chance for a species to survive over time through natural selection.
- Species diversity allows more organisms to fill niches.
- Ecosystem diversity makes it so that everything doesn't live in the same place, resulting in higher resources. Biodiversity is diminished by:
- Habitat loss.
- Overhunting/overfishing.
- Climate change.
- Invasive species.
- Monocultures. Monocultures are when only one type of plant is farmed. Effects of monoculture:
- Reduced biodiversity.
- Soil degradtion.
- Increased pests/disease risk.
