How organisms interact with eachother and their environment

Producers (Autotrophs)

Make their own food

Primary consumers

Herbivores or omnivores that eat producers

Secondary consumers

eat primary consumers (can be carn or omni)

Teritiary consumers

Top of chain

Food webs

links many food chains together, shows how organisms interact with eachother, arrows show energy flow

Energy pyramid

Shows how much energy is vailable at each trophic level, as u move up the pyramid, energy decreases

Ecological niche

full range or physical and biological conditions an organism needs (food needs, habitat, role in ecosystem)

Competition

When organisms need the same resources

Predation

Predator killls and eats prey

Mutualism

Both benefit

Commensalism

one benefits, other is unaffected

Parasitism

Parasite benefits, host is harmed

Exponential growth

Population grows rapidly

Logistic growth
