Herbivores (primary consumers)
Dependent Variable
Carnivore
photosynthesis
Zooplankton
Decomposers
Independent Variable
Consumer (heterotrophs)
Omnivores
Oxygen
Producers (autotrophs)
Glucose
Controlled Variable
Required for photosynthesis
Phytoplankton
Organisms that eat both plants and animals
A process used by plants to acquire their own energy.
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
Carbon Dioxide, water, and sunlight
Organisms that eat only consumers.
Organisms that get their energy by breaking down dead organisms and animal wastes AND make nutrients in the soil.
A waste product produced by plants during photosynthesis
A sugar produced during photosynthesis by producers
Organisms that cannot produce their own food and must eat to get energy
Variable that we make the same in an experiment
Tiny organisms usually found in large bodies of water that consume other small organisms.
Organisms that get their energy from the sun through photosynthesis
Variable we make different in an experiment or test.
Organisms that only consume producers.
