Matching Pairs Producers Consumers and Decomposers 2Online version assignment by Benjamin D Morgan 1 Dependent Variable 2 Independent Variable 3 Oxygen 4 Controlled Variable 5 Omnivores 6 Phytoplankton 7 Consumer (heterotrophs) 8 Carnivore 9 photosynthesis 10 Decomposers 11 Zooplankton 12 Producers (autotrophs) 13 Required for photosynthesis 14 Herbivores (primary consumers) 15 Glucose Organisms that cannot produce their own food and must eat to get energy Variable that we make the same in an experiment Carbon Dioxide, water, and sunlight Organisms that eat only consumers. A waste product produced by plants during photosynthesis Organisms that only consume producers. Organisms that get their energy by breaking down dead organisms and animal wastes AND make nutrients in the soil. A sugar produced during photosynthesis by producers Organisms that get their energy from the sun through photosynthesis Organisms that eat both plants and animals A process used by plants to acquire their own energy. Tiny organisms usually found in large bodies of water that consume other small organisms. Variable we make different in an experiment or test. Tiny photosynthetic organisms usually found in large bodies of water and are the most common producers in these waters Variable that we measure during an experiment
