Reptiles and birds excrete waste as an insoluble white solid that is called uric acid. how does this them maintain internal homeostasis in hot climates

Most of the mammals excrete urine in the form of water along with nitrogenous wastes dissolved in it. This removes water from the body and if there is a constant loss of water from the body then there will be dehydration in the body.

In case of birds and reptiles they excrete the waste out of their body in the form of semi solid matter which does not includes water.

This prevents the loss of water from the body and in this way it helps in maintaining the internal homeostasis of the body.

i think that it is plants

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.
