Why would snails loose energy if a a disease killed all hedgehogs?

If all hedgehogs were to be wiped out by a disease, snails might lose energy due to a potential increase in their population, leading to higher competition for limited resources such as food and habitat. Additionally, without hedgehogs to control their numbers, snails may face a denser environment that could result in increased stress and reduced access to nutrients. This stress and resource competition can ultimately lead to energy depletion and lower overall health for the snail population.
