Study Notes
Ecology and Ecosystems
- Ecology is the study of the interactions between organisms and their environment.
Ecosystems
- An ecosystem is a community of living and non-living components interacting with each other in a specific environment.
- An ecosystem consists of biotic factors (living organisms, such as plants, animals, and microorganisms) and abiotic factors (non-living components, such as water, sunlight, and soil).
Biogeography
- Biogeography is the study of the distributions, abundance, and relationships of organisms.
Biomes
- Biomes are classified fundamentally based on climate.
