Presentation transcript:

Energy Flow

All energy in an ecosystem comes from…….

Producers Producers- (autotrophs) make their own energy Turn the suns energy into a form other organisms can obtain Ex. plants, some bacteria, algae

Consumers Consumers- (heterotrophs) get energy from other organisms Get energy through eating or absorption (5 kinds) Ex. animals and fungi

Herbivores Eat plants Ex. millipedes, rabbits, elephants, sloths, pandas, crickets,

Carnivores Eat meat Ex. cats, dogs, centipedes, sharks, seals, hawks

Omnivores Eat plants and animals Ex. Bears, raccoons, crows, primates

Decomposers / Detritivores Scavengers They eat dead and/or decaying matter Ex. vultures, crab, maggots, dung beetle, bacteria

Food Chain Graphic display of who eats who in an ecosystem Arrows represent the direction of energy flow

Food Web Animals feed on more than one species A food web is a display of interconnected food chains

Trophic Level A group of animals that get their energy from the same source (the sun, plants, rodents, snakes, bugs etc). Describes an organisms position in the food web

Energy Pyramid Only 10% of the energy passed up trophic levels makes it to the next level Energy pyramids display this principle
