| #1 | Where are producers on the energy pyramid ? |
Always at the base |
| #2 | What do second level consumers eat ? |
They eat first level consumers. |
| #3 | How do decomposers connect the food chain ? |
They break down the tissue of the dead organisms. They use some of the nutrients from the dead tissue as food. The rest becomes part of the soil. |
| #4 | Where are producers on the energy pyramid ? |
Always at the base |
| #5 | What is the difference between energy pyramids with pyramids of numbers.
|
The difference between a pyramid of numbers and an energy pyramid is that a pyramid of numbers is related to population size in each trophic level, an energy pyramid shows the amount of energy left by each trophic level. |

| #1 | What do consumers eat ? |
They eat Producers |
| #2 | What do omnivores eat ? |
They eat from any level. |
| #3 | Define trophic level. |
The trophic level of an organism is its position in the food chain. Producers, primary consumers, secondary consumers and tertiary consumers are examples of trophic levels. |
| #4 | What is a food chain? |
The food chain is the linear not branched sequence in which a living being serves as food for another, starting with the producers and going up to the decomposers. |
| #5 | If birds eat insects that feed on corn, which pyramid level would birds occupy? |
The answer is B!!
It's easy huh? |
| Final Question | |
As one progresses from level D to level A in this pyramid, what happens to the amount of stored energy?
|
It decreases |
