structual adaption..

A

features of organism body like shape or colour

39

A

they have to maintain an internal body tempreture and generate their own heat ( so they ccan be warm in cold places )

45
Q

what is an ectotherm

they do not maintain constant body temp and they have to adapt and go to places to get the heat or cold they want ( like the sun or shade)
