1. Explain why predators need to eat more than primary consumers.  

Explanation:

Predators need to eat more than primary consumers because in the trophic pyramid, primary consumers are at the bottom which means they receive the most energy because they eat the plants. As the pyramid goes on upwards, energy is lost each time, so that means by the time it reaches the top of the pyramid their is only about 0.1% of the energy we started with when the primary consumers ate the producers. Meaning, the predators need to eat more than the primary consumers because although the predators eat more than the primary consumers, they still at the end of the day get the same amount of energy just one eats more than another.
