Study Notes
Community Ecology
- Community interaction involves different species living in the same area, influencing each other's survival and reproduction.
Types of Community Interactions
- Predation involves one species consuming another species for food.
Intraspecific Competition
- Occurs between individuals of the same species, competing for limited resources such as food, water, and mates.
Community Dynamics
- Refers to the changes in species composition, structure, and function over time in a biological community.
Keystone Species
- Characterized as a species that has a disproportionate impact on its environment and plays a crucial role in maintaining the structure and function of its ecosystem.
Primary Succession
- The process of ecosystem development on new, uninhabited land, such as after a volcanic eruption or glacial retreat.
Biological Community vs. Ecological System
- A biological community refers to the interacting species in a specific area, while an ecological system includes both the community and its physical environment.
Natural Resources and Species Composition
- Natural resources can impact the species composition, structure, and function of a community by influencing the availability of resources such as light, water, and nutrients.
Importance of Community Interactions
- Community interactions are crucial for maintaining ecosystem balance, as they influence the survival and reproduction of species, and can favor or eliminate biological species.
