20. Food Chain  Autotrophs, also known as producers, make up the first level in all food chains which include plants and some aquatic photosynthetic plants. Exs. Grass and Green algae  1 st -order-heterotrophs, also known as primary consumers, make up the second level in a food chain and obtain food from photosynthetic organisms. Ex. Turtle

21. Food Chain  2 nd - order heterotrophs also known as secondary consumers, include some carnivores who feed on 1 st -order heterotrophs. Ex. Owls feed on fishes  3 rd - order heterotrophs also known as tertiary consumers, include carnivores (meat eaters) Ex. Bears

22. Food Chain  Decomposers - at every level in food chain, bacteria and fungi break down living matter and help release nutrients
