i know it not A or B

Answer 2

An ectotherm is a creature that relies on external sources for heat. The method for temperature regulation depends on what type of creature it is. Reptiles such as snakes will move out into the sun to get warm and move into the shade when they need to cool down. In desert climates, a snake will likely move on top of a rock in the evening to keep warm until the absorbed heat has left. Amphibians may move out into the sun or get into warm waters, then find shade to cool down. Insects like bees may regulate their temperatures by huddling together for warmth via body heat and gather water using their wings as fans to get cool again. Flying insects typically stretch their wings into the sun and reflect heat through them onto the body, such as with a dragonfly.
