The bird makes a hole in the cactus so that it could live in. so there for it benefits off the cactus for use of a home and the strength off the cactus helps it not to be harmed in the process. So one organism benefits while the other one is not affected
The antelope is being cleaned by the bird and the bird is being fed at the same time neither animal is getting harmed matter of fact the both benefiting off echother to survive
The wasp stings the spider just long enough to lay eggs in the spider so that when the wasp babies grow they have something to feed off the wasp is benefiting off the spider so that it has a place to lay eggs the spider is deathly harmed in this cycle
How humans are Impacting the Desert
Humans have been drilling holes for natural resources and hunting unique animals that to this day are already extinct because of us we have been polluting the environment and harming the things that live there but we have done some good things such as bring more people to live in such desert like places and we have discovered all types of new thing we have took thousands of pounds of sand from the deserts to spread it to other places so there are the negative impact and positive impacts on the deserts.
