Welcome to Biology Regents Review… Session 2 Today’s date: ________________ Topics: Feeding relationships, food webs, biomes, part of cells Feeding relationships ____________________: ____________________: ____________________: Maple tree makes its own food during photosynthesis (autotroph) eats producers only only eats other consumers Mushroom Examples (primary consumer – a special type of heterotroph) Hyena (meat eater – another special type of heterotroph) Examples Lion Sea gull Examples Algae ____________________: ____________________: ____________________: Skunk eats both plants and animals feeds on the dead remains of plants and animals that it did not kill breaks down the dead or decaying remains of other organisms returning their nutrients to the ecosystem Bear Examples Examples Examples Corn Crayfish Soil bacteria Food webs Can you list the 5 possible food chains shown in the food web diagram to the right?
