Term
| What is the difference between a food web and a food chain? |
|
Definition
| A food chain shows only one series of energy transfers as organisms eat but a food web shows all (or at least many) of the the energy transfers in the ecosystem. |

Term
| What is the carrying capacity of a population? |
|
Definition
| This is the point at which the population size levels off because of limiting factors such as available food and water. |
|
|
Term
| What does a j-shaped curve show on a population graph? |
|
Definition
| This shows exponential growth of a population (rapid increase in population size). |
|
|
Term
| What does an s-shaped curve show on a population graph? |
|
Definition
| This shows an initial increase in population growth but then the growth of the population slows as it reaches the carrying capacity. |
