Study Notes
Ecosystems
- Definition: A community of living (biotic) and non-living (abiotic) components interacting with each other in a specific environment.
- Components:
- Biotic factors: plants, animals, microorganisms
- Abiotic factors: light, temperature, water, soil, air
- Types of ecosystems:
- Terrestrial: forests, grasslands, deserts
- Freshwater: rivers, lakes, wetlands
- Marine: coral reefs, estuaries, open ocean
- Arctic/Antarctic: tundra, ice sheets
Biodiversity
- Definition: The variety of different species of plants, animals, and microorganisms that live in an ecosystem or on Earth as a whole.
- Types of biodiversity:
- Genetic diversity: variety of genes within a species
- Species diversity: number of different species in an ecosystem
- Ecosystem diversity: variety of ecosystems in a region
- Importance of biodiversity:
- Maintains ecosystem services: pollination, pest control, climate regulation
- Provides medicinal and food resources
- Supports human well-being and quality of life
- Threats to biodiversity:
- Habitat destruction and fragmentation
- Climate change
- Overexploitation of resources
- Invasive species
- Pollution
