This document defines key terms related to food chains, food webs, and energy pyramids. It explains that energy from the sun is transferred through a food chain from producers to consumers. The number of organisms decreases at each level of an energy pyramid as more energy is used and stored, rather than transferred. Different biomes like polar regions, deserts, and forests each have their own characteristic food chains and webs.

2. Vocabulary 23: Food Chain/Web/Energy Pyramid --Biotic factor living factors in an environment that affect living things --Abiotic factor nonliving factors in an environment that affect living things --Ecosystem a group of animals and plants interacting with each other and the environment --Predator: an animal that hunts and eats other animals --Prey: an animal that is hunted and eaten for food --Decomposer: animals that eat & break down dead things into soil nutrients

3. Vocabulary 24: Food Chain/Web/Energy pyramid Consumer : Something that takes in other things Producer : something that makes or produces something Scavenger: an animal that eats dead animals that something else has already killed Omnivore : an animal that eats both plants or animals Carnivore: an animal that only eats meat (other animals) Herbivore : an animal that only eats plants

4. DEFINITION: Food Chain (food web) : The relationship of animals eating plants and then each other from the ‘bottom’ to the ‘top’ Energy Pyramid (energy web) the transfer of energy from bottom of the pyramid to the top

5. Rules: Energy starts with the sun FOOD CHAIN www.yvonnegraphy.com/2008/08/29/food-chains/

6. Rules: 2. Number of organisms go down as you go up the pyramid (fewer predators) 3. Amount of Energy decreases as you go up the pyramid (organisms use some of it while living, stores rest in tissues) 4. Therefore the community can support fewer predators than prey or producers ENERGY PYRAMID
