Study Notes
Symbiotic Relationships
- Symbiosis describes relationships between organisms of different species.
- Types include:
- Mutualism: Both species benefit (e.g., oxpecker and zebra).
- Commensalism: One species benefits, the other is unaffected.
- Parasitism: One species benefits, the other is harmed.
Environmental Science
- Environmental science studies natural processes and human impact.
- Biodiversity refers to the variety of species in an environment.
- Climate influences species distribution (e.g., species richness increases towards the equator).
- Niche diversity describes areas with a single species.
- Niche: An organism's role and adaptations in its habitat.
- Keystone species significantly influence ecosystem dynamics.
- Extinction: Complete disappearance of a species.
- Endangered species face extinction.
- Threatened species are at risk of endangerment.
Natural Resources
- Natural resources are environmental materials used by people.
- Renewable resources are replenished relatively quickly.
- Non-renewable resources are not replaced within a human lifetime (e.g., oil, coal).
Adaptations and Evolution
- Adaptations: Features and behaviors enabling species survival in their environment.
- Ecological adaptations: Body features, actions, abilities helping organisms in their environment.
- Natural selection: Traits enhancing an organism's survival in its environment.
- Competition: Struggle for resources (food, water).
- Predation: One animal hunting and consuming another.
