How can sunlight affect an ecosystem?
Provide energy
Why is competition usually strongest between the same species?
Need the same recources

Resources are limited
What is the difference between a habitat and a niche?
Habitat: Where organisms live
Niche: Role on the environment
A forest has deer, wolves, trees, soil, and water. What organization is this?
Ecosystem
Why are abiotic factors important to organisms?
Influence where organisms can survive
What is resource partitioning?
Species share resources to avoid competition
How is niche's differences can reduce competition?
Differences in niches reduce overlap in resources and lower competition
