Answer 1

In an energy pyramid, approximately 10% of the energy from one trophic level is passed on to the next level. This is often referred to as the "10% Rule."

Here’s how it works for each level:

1. **Producers (First level)**: 100% of the energy is available.
2. **Primary Consumers (Second level)**: About 10% of the energy from producers is passed on (10% of 100% = 10%).
3. **Secondary Consumers (Third level)**: About 10% of the energy from primary consumers is passed on (10% of 10% = 1%).
4. **Tertiary Consumers (Fourth level)**: About 10% of the energy from secondary consumers is passed on (10% of 1% = 0.1%).

To summarize, each level retains about 10% of the energy from the level below it.
