| Food pyramid | a diagram to show how the amount of food energy available changes ay each step of the food chain. |
| Amount of Food | The differences in the size of population. |
| Energy Flows | Goes from thing to thing. |
| Limiting factor | a factor that controls the number of living things that an ecosystem can support. |
| Carrying capacity | the maximum number of living thing that a givin ecosystem can support with out danger to the surarval of the living things. |
