MATERIALS AND METHODS Lactate dehydrogenase … WebMost ectotherms do regulate their body temperature to some degree, though. They just don't do it by producing heat. Instead, they use other strategies, such as behavior—seeking sun, shade, etc.—to find environments whose temperature meets their needs. Each of the categories above is called a trophic level, and it reflects how many tra… WebWhile many insects are ectotherms(animals in which their heat source is primarily from the environment), others are endotherms(animals that can produce heat internally by biochemical processes). These endothermic insects are better described as regional heterothermsbecause they are not uniformly endothermic. cryptographic prng
