Community
On what scales do communities occur?
Small pond communities to huge tropical rainforests
What type of systems can be considered as ecosystems?
Systems containing interacting biotic and abiotic components

Ecosystem
Study Notes
- Ecology recognizes several hierarchical levels of organization to study organism-environment interactions
- Four fundamental levels of ecological organization: individual organism, population, community, and ecosystem
- Individual organism level deals with how individual organisms are affected by and impact their environment
- Population level, a group of same-species individuals in a given area, interacts with other populations and population growth and change
- Community level, a group of interacting populations of different species, forms a complex system at a defined geographical area
- Ecosystem level, a system of interacting biotic and abiotic components, deals with energy flow and nutrient cycling within a community and environment.
Explore the hierarchical levels of organization in ecology to understand how organisms interact with each other and their physical environments. Ecological patterns and processes vary across different levels of organization, influencing the interactions between organisms and their environment.
