experiment
independent variable - ANSWERSthe manipulated variable
dependent variable - ANSWERSthe responding variable
homeostatis - ANSWERSinternal stability in the body
organic molecules - ANSWERSproteins, nucleic acids, lipids, carbohydrates
autotrophs - ANSWERSorganisms that can capture sunlight or chemicals and use that
energy to produce food.
heterotroph - ANSWERSorganisms that rely on other organisms for food and energy
producers - ANSWERSproduce their own food
consumers - ANSWERSalso called heterotroph
biogeochemical cycles - ANSWERSwhen elements are passed from organism to
organism through the biosphere
limiting nutrient - ANSWERSwhen nutrients are limited in an environment
