Certain
toxic mushrooms have bright, distinctive colors than mushroom-eating animals
learn to recognize. Once sickened, day-feeding animals tend to avoid them.
Other toxic mushrooms are as dull-looking as edible ones, but they have a much
stronger odor. Some scientists think the strong odors aid in defense against
predators that are active at night. Explain their reasoning.

At night, animal's vision is affected because of the darkness. bright distinctive color of a toxic mushroom will not affect the predators  because they cant see it ,while the dull looking mushroom affects its predator by their scent,so its defense are not affected by the darkness.
