Introduction to Ecosystems

Ecology Ecology is the study of the relationships between biotic and abiotic factors

What is an ecosystem? An ecosystem is composed of all the factors (both biotic and abiotic) and interactions in an environment.

Biotic vs. abiotic Abiotic factors of an ecosystem are non-living. Biotic factors of an ecosystem are living. rocksairwater animalsbugsbirdsplants temperature

Biotic parts of an Ecosystem Living things are either consumers or producers. Producers make (or produce) their own food. Example: plants Consumers need to eat (or consume) their food. Example: animals

Consumers There are several different kinds of consumers: – Herbivores: eat plants only Example: deer – Carnivores: eat animals only Example: wolf – Omnivores: eat plants and animals Example: raccoon – Decomposers: break down dead things Example: bacteria and fungus

Decomposers Scavengers: – eat dead animal and plant matter Detritivores : – Eat detritus (decomposing matter) – Ex. crabs, earth worms, insects that eat decaying wood Saprotrophs : – break down dead or decaying organisms outside of their body and consume what they need. * Humus: Soil material made of plant and animal matter undergoing decomposition.

Food Chain A food chain is a single chain of organisms (living things) that eat each other. The chain ALWAYS starts with a producer.

Food Web A food web is made out of many food chains in an ecosystem.

Questions to think about … 1) What does “ bio ” mean? 2) Are people herbivores, omnivores, or carnivores? 3) What is more realistic – a food chain or a food web? 4) Why does a food chain always start with a producer?
