| 3 methods used to study nature | observing, experimenting, modeling |
| producers are | makes own food |
| consumers are | consume food |
| herbivores are | plant eaters |
| carnivores are | meat eaters |
| omnivores are | eat both plant and animals |
| decomposers are | break down organic matter |
| autotrophs are | makes own food |
| heterotrophs | do not make their own food |
| an ecological pyramid is | shows what things eat what, amount of energy, biomass decreases as you go up |
| biomass is | the total amount of living tissue |
| flow of energy in a food chain | shows the flow of energy going toward organism getting the energy |
| how does carbon dioxide get into atmosphere | animals, cars, volcanoes, industry |
| why is nitrogen important to living organisms | helps organisms make proteins/amino acids |
| phosphorus is in this organic compound | DNA and RNA |
| parts of the water cycle | evaporation, condensation, transpiration, precipitation, runoff |
| primary consumer is | eat plants |
| secondary consumers are | eats other organisms |
| difference between food chain and food web | food web is made of interconnecting food chains, |
| what happens to biomass as you go up the pyramid | because there is less energy |
| always on the bottom of pyramid | producers because they make their own food |
| where do producers get energy to make food | sun |
