ECOLOGY What is ecology the study of?

Ecology The scientific study of interactions between different kinds of living things and the environments in which they live.

‘Eco’ stands for the Greek word ‘oikos’ logy = _________

Why Care About Ecology? Ecological research provides us with the necessary info. to resolve many of the environmental problems that surround us.

We are dependent upon the world’s ecosystems, therefore, we must learn how to keep the environment safe for all living organisms.

Ecosystem A particular environment in which a group of organisms live (broad area)

Habitat Localized, or smaller version of an ecosystem

Ecosystems are made up of two factors… Biotic (living) Abiotic (non-living)

Biomes A local habitat characterized by its climate, & therefore by the organisms that live there.

Desert, rainforest, tundra, arctic, temperate forests, etc. Examples of Biomes Desert, rainforest, tundra, arctic, temperate forests, etc.

Biodiversity Biological diversity is one of the most important, yet much ignored resources on our planet

Biodiversity is the genetically based variety of living organisms in the biosphere. Biodiversity is important for many reasons including agriculture, medicine, and recreation.

Biodiversity is connected to ecosystem diversity, both of which are being destroyed.

Energy Flow in Ecosystems Food Chain vs Food Web… Autotroph:__________________ Heterotroph:________________ Herbivore, omnivore, carnivore, decomposer

Energy in trophic levels _____________ as you move up the pyramid Biomass __________________as you move up the energy pyramids

Biogeochemical Cycles (Nutrient Cycles) Carbon Water Nitrogen
