Warm-UpWarm-Up:: Levels of an Ecosystem Levels of an Ecosystem
Label each descriptions as a population, community, or ecosystem.
1. Owls, mice, and grass all live in one area.
2. Owls, mice and grass all live in an area near a pond that receives lots of sunlight.
3. Eight owls all live in one area.

Relationships in an EcosystemRelationships in an Ecosystem
• 3 types of relationships:
predation
competition
symbiosis

Predation Predation = = one organism is a one organism is a food source for another organismfood source for another organism
Predator = hunter
Prey = food

Symbiosis Symbiosis = relationship between = relationship between 2 organisms that benefits at least 2 organisms that benefits at least 1 of the organisms1 of the organisms
• 3 types of symbiosis:
mutualism
commensalism
parasitism
