Energy Flow Sunlight is the main source of energy for life on Earth.
Chemosynthetic Organisms Some organisms rely of inorganic chemicals rather than the sun for energy. All bacteria, manufacture carbohydrates and other organic molecules from the oxidization of sulfates or ammonia.
Autotrophs Organisms that use sunlight to produce energy. Use inorganic compounds to make organic molecules. PLANTS Also called PRODUCERS
Photosynthesis Process by which autotrophs harness sunlight in a chemical reaction to change inorganic compounds into energy-rich carbohydrates and oxygen.
Heterotrophs Organisms that rely on energy from other organisms Also called CONSUMERS
Types of Consumers Herbivores – eat only plants Carnivores – eat animals Omnivores – eat both plants and animals Detritivores – feed on animal remains and dead matter Decomposers – break down organic matter
Detritivores Spaghetti worms have tentacles range out from a burrow in rock or sediment to collect the small particulate detritus that the worm feeds on. amphipods tearing plant debris and organic detritus into "bite sized" pieces and eating it
