Snails are important because without them the enemies of a snail wouldn't
have anything to eat, then the predators who eat snails wouldn't have enough
food to eat then there will be less and less of them, and then the predators
who eat the enemies of a Snail would not have enough food and so on so its a chain reaction, you change one thing the whole thing is effected.
snails are very senstive.
It depends on the environment. Snails are very common in moist, damp areas, yet sparse in hot dry climates.
snails
In general, water snails predate upon plants. They do not help them they destroy them.They dont help and they dont harm
There are beneficial snails and problem snails. Good snails would be welcomed in a pond setting as they would help control algae growth. Problematic snails over populate their habitats.
Water snails have heavy shells that help keep them on the bottom.
Humans, Zebra Snails and Communists
leaves
mucus helps snails to move because its sticky. its also slimy. these to things help the snail to move over different surfaces
They do it the same way we do, using intestinal peristalsis to move the fecal matter out through their anal sphincter. After that, it falls to the floor of their environment to be incorporated into the environment.
Sometimes, if they cannot find a shady moist environment soon enough, they will die. Some snails have the ability to seal up their shell opening with hardened mucous. This helps them retain moisture hopefully waiting for their environment to become moist again.
No all they eat is left overs from the fishes as for land snails they eat plants and leaves
