Interdependence
Key Theme in EcologyCrucial interactions occur
between organisms and the living and nonliving
environment.

Why is the amount of sunlight important to
animals in an ecosystem?

Ecosystems
Shaped by Biotic and Abiotic Factors

Biotic Factors• Community interactions:–Competition• Competitive Exclusion Principle
–Predation–Symbiosis•Mutualism• Commensalism• Parisitism

Abiotic Factors• Climate• Temperature• Precipitation• Sunlight• Geographic distribution• Soil• Elevation

Survival
Optimal range Tolerance limitsAcclimation (not adaptation)

Internal controlConformers (cold-blooded )
Regulators (warm-blooded)
Escape Short/long term DormancyMigration

Why do different species never occupy
exactly the same niche?

A small rodent species and a bird species are
adapted to cold temperatures. How might each species
survive a major temperature increase?
