Study Notes
Ecosystem Basics
- An ecosystem combines biotic (living) and abiotic (non-living) components.
- Biotic parts include plants, animals.
- Abiotic parts include temperature, water, soil, and air.
Populations in an Ecosystem
- A population consists of all organisms of the same species in a specific area.
- Communities are groups of different populations within an ecosystem.
- Organisms occupy different niches in the same environment.
- Similar niches can lead to competition due to shared resources.
Ecosystem Diversity and Health
- High biodiversity provides more resources.
- Biodiversity helps resources last longer.
- Less diverse ecosystems have reduced competition.
- South American rainforests display a strong relationship between ecosystem diversity and health.
Abiotic Factors in Ecosystems
- Abiotic factors like temperature, water, soil, and air influence an ecosystem.
- These factors affect which species can survive and thrive.
- Abiotic factors affect the rate of seasonal changes and the communities present.
- Abiotic factors directly affect how humans can influence ecosystems.
Limiting Factors of Ecosystems
- Limiting factors restrict population size.
- Limiting factors include resources, space, and predators.
- Limiting factors influence plant and animal development and growth.
- Limiting factors include animal maturity rates.
