Biodiversity
•The variety of living things in a particular area.
Ecosystems
•The focus of all ecosystems is food.
•Energy is passed on by food.
Trophic Levels
•Autotrophs (producers):▫Make their own food using energy from the
sun. ▫Ex. Plants, algae, bacteria
Trophic Levels
•Heterotrophs (consumers): ▫Need to eat other organisms to get energy.
▫Herbivores: Eat plants, algae, bacteria▫Omnivores: Eat plants and animals▫Carnivores: Eat animals only
Trophic Levels
•Scavengers: ▫Eat dead material. ▫Ex: lobster, shrimp
•Decomposers:▫Break down dead material. ▫Ex. Bacteria
Food Chains
•Energy is recycled through the trophic levels.
Food Chains
•The arrows show the direction of energy flow.
•They always begin with a producer.
Food Web
•Shows many food chains interacting in an ecosystem.
