An example of a physical adaptation of an animal in a desert ecosystem would be when an organism —

has sharp claws for gripping and climbing tall trees

is only active at night to avoid the extreme heat of the day

hibernates through the summer to avoid the heat

remains cool due to large ears that encourage evaporation

of heat from the body.
