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