Study Notes
Ecology and Ecosystems
- Ecology is the scientific study of the interactions between organisms and their environment.
- An ecosystem is a community of living and non-living things, such as plants, animals, microorganisms, water, sunlight, and soil, that interact with each other in a specific environment.
- An ecosystem consists of biotic factors (living things) such as plants, animals, and microorganisms, and abiotic factors (non-living things) such as sunlight, water, temperature, and soil.
- The main focus of ecology is to understand the relationships between organisms and their environment, and how they affect each other.
Biomes
- Biomes are large, naturally occurring communities of plants and animals that occupy a specific habitat.
- The fundamental classification of biomes includes:
- Terrestrial biomes (land-based ecosystems)
- Freshwater biomes (rivers, lakes, and wetlands)
- Marine biomes (oceans and seas)
- Atmospheric biomes (air and weather patterns)
- Arctic is NOT a fundamental classification of biomes.
