PLS DO NOT PUT A LINK IT IS A VIRUS Which factor can increase both potential energy and kinetic energy of an object?

Increase in speed
Increase in mass
Decrease in temperature
Decrease in height from the ground

Imagine you have a five-step food chain. If 100 percent of the energy is available at the first trophic level, what percentage of energy is available at the highest trophic level

Explanation:

hope this helps
