Study Notes
Ecosystem Basics
- An ecosystem is a community of living and non-living things interacting with each other in a specific environment.
Energy Source
- The main source of energy for most living things in an ecosystem is sunlight, which is used by producers (plants and algae) through photosynthesis.
Trophic Levels
- The first trophic level in an ecosystem is occupied by producers (plants and algae), which produce their own food through photosynthesis.
- The second trophic level in an ecosystem is occupied by primary consumers (herbivores), which feed on producers.
Feeding Groups
- The term used to describe the different feeding groups in an ecosystem is trophic level.
