Food Chains & Webs

• Food chains show the movement of energy through the trophic levels of organisms with picture and arrows.
• Food chains start with producers.
• The trophic level of an organism indicated the position of the organism in the food chain. (1=producer, 2=primary consumer, 3=secondary consumer etc.)
• Primary consumer = eats producers (herbivore/omnivore)
• secondary consumer = eats primary consumer (carnivore/omnivore)
• tertiary consumer = eats secondary consumer
• Earth's recycling center is through decomposers and primary producers.
• Food webs describe the organisms found in interconnecting food chains.
