Question

if all the rocks are removed from a desert ecosystem, what would happen to the population of rock dwelling lizards and in turn the animals which eat them?

Answer 1

What happens when you remove a large family from their home? They start to scatter, looking for more land to live in/on. By removing rocks in a desert ecosystem, you're removing the lizards natural habitat. This causes many things to happen like taking away hiding places, a cool rock to sleep under during the day or easy land to dart over. This will also effect their predators in good and bad ways. Good because it'll be more for them to catch but bad because that could also be their natural habitat. Their's a chain reaction of problems that could happen.

Answer 2

if there are no rocks in a desert then the prey would rapidly decrease due to no rocks for shelter or hiding, once they do food will be scarce for the predators causing the predator population to also decrease meaning that the life in the desert will decrease by 80%, leaving barely any wildlife left.
