The snail needs its food to have the ability to have energy and live. The turtle relies on the snails, so if the snails die, the turtles will eventually die off, or the population will decrease as well!
explanation: if marsh snails’ eat phytoplankton and phytoplankton were destroyed, that would decrease marsh snails population because they have no food. Painted turtles would also decrease because they would have no marsh snails to eat.
