Big Concepts in Ecology
• Energy moves in one direction, constantly being
added by the sun, it is NOT recycled
• Materials (water, nutrients, carbon) cycle
through an ecosystem
• Abiotic factors are nonliving (water, light)
• Biotic factors are living (predators)
• Biotic and Abiotic factors keep populations
from growing too big; all ecosystems have a
carrying capacity
• When organisms interact it can be positive or
negative

Big Concepts in Ecology
• All stable ecosystems need more autotrophs
than heterotrophs AND they need
decomposers to recycle nutrients back to soil
• All stable ecosystems have high biodiversity
• Each organism has its own niche, to avoid
competition
• Ecosystems that change suddenly usually
return to their original state by succession,
leading to a more stable community

• Autotroph: makes its own food
• Decomposer: breaks down dead
materials
• Herbivore: eats only plants
• Carnivore: eats only animals
• Omnivore: eats both plants and animals

human overpopulation (due to better
