Energy Flow In Ecosystems Ch. 5 sec. 1 Ultimate source of Energy Sun Plants use sun and animals rely on plants Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen. Producer An organism that makes its own food also known as autotrophs Consumer Organisms that get their energy by eating other organisms also known as heterotrophs Cellular respiration What eats what Herbivores = plant eaters Carnivores Meat-eaters Omnivores Eat both plants and animals Decomposers Break down dead organisms causing them to rot or decompose Very important to life cycles Respiration Cellular Respiration = breaking down food to produce energy Food Chain A sequence in which energy is transferred from one organism to the next Food Web Many of the feeding relationships in an ecosystem Trophic Levels Each step in the transfer of energy through an ecosystem Only 10% of energy is actually transferred
