Producers & Consumers

Learning Objectives Identify the source of energy for life processes Compare and contrast autotrophs and heterotrophs

Energy Flow All living things need energy to survive

Sunlight Sunlight is the main energy source for life on Earth

Organisms are divided on how they obtain energy Autotrophs Heterotrophs

Autotrophs Autotrophs - make their own food for energy using sunlight or chemicals. AKA producers

Heterotrophs Heterotrophs - organisms that rely on other organisms for their energy and food supply. AKA consumers

Herbivore Herbivore - Eats only plants. Examples: deer, squirrel

Carnivore Carnivore - eats other animals Example: Tiger, Hawk

Omnivore Omnivore - eats plants and animals Examples: Humans, Bears

Detritivores Detritivores - feeds on the bodies of dead matter Decomposers - break down organic matter Scavengers - feed on dead/dying animals
