Carbon dioxide cycle | exchange of carbon dioxide and oxygen from one organism to another |
carbon dioxide | gas needed by plants to makie food |
decomposer | organisms that get energy by causing dead organisms to decay |
consumers | organisms that get their energy from other organisms |
germination | sprouting of new plant structures |
water cycle | the circular pathway in which water moves through an ecosystem |
transpiration | process by which plants give off water from their leaves |
larva | young animal that looks completely different from its parents |
metamorphosis | the complete change of an organism's body from one form to another form |
pupa | stage after the larva stops feeding, in which many changes take place |
producer | green plants that use the sun's energy and other substances to make their own food |
energy pyramid | shows the flow of energy from sun to plants to animals |
life cycle | stages that living things go through |
oxygen | gas needed by animals to use energy |
1st level of pyramid | sun |
sun | the main source of energy for the producers |
2nd level | producers |
producers | bring energy from nonliving sources into the community (from the sun) |
3rd level | primary consumers |
primary consumers | get energy from the producers, which makes them herivores in most communities |
4th level | secondary consumers |
secondary consumers | get energy from the primary consumers, which makes them carnivores |
tertiary consumers | get energy from the secondary consumers |
primary consumers are herbivores or carnivores? | herbivores |
secondary consumers are herbivores or carnivores? | carnivores |
