If an animal goes extinct in a food web, what would happen to the other creatures that EAT that organism?

(word your answer)

Their population may decrease due to losing a food source.

If someone is at the top of a roller coaster do they have HIGH Gravitational Potential Energy (GPE) or LOW GPE

HIGH GPE - because the higher the height of something, the greater the potential energy as seen in the equation:

GPE = m x g x h

If an animal goes extinct in a food web, what would happen to the other creatures that GET EATEN by that organism?

(word your answer)

Their population may increase due to having less predators.
