- Biotic components: living organisms including producers, consumers, and decomposers
- Interactions between abiotic and biotic components shape the ecosystem
Ecosystem Classification
- Terrestrial ecosystem: a type of ecosystem that exists on land, including forests, grasslands, and deserts
- Other types of ecosystems: aquatic ecosystems (freshwater and marine), and atmospheric ecosystems

- Producers: organisms that make their own food through photosynthesis, such as plants and algae
- Consumers: organisms that obtain energy by consuming other organisms, including herbivores and carnivores
- Decomposers: organisms that break down dead organic matter, such as bacteria and fungi
