Answer:
The mouse would suffer the most if plant life died in the desert, due to it being an herbivore. If the mouse was in a desert with no plant life, it would most likely suffer from dehydration. Without any water to drink, its body temperature would drop and eventually it would die. The same goes for if there were no plants or animals in the desert; mice are very sensitive to changes in their environment, and they need a constant supply of food to survive. If there is nothing that they can eat, then they will most likely die of starvation. And when the mouses all die out, then other animals that depend on them including predators, would either go find a new place to find food or die of starvation due to lack of prey. In the end, almost all animals would suffer because if there are no plants then animals like herbivores would mostly die and when there are no prey or animals for predators to eat, then they too will die of starvation.
Step-by-step explanation:
In the desert, there are a couple of plants that can survive for long periods of time. These include cacti and succulents. When these plants die, the animals that depend on them become very hungry or go extinct. The most vulnerable animal would be the mouse because this species is extremely sensitive to changes in temperature. This means that it will not have enough water to drink or food to eat if temperatures get too hot in the desert.
