Answer:
basking on black rocks.
Step-by-step explanation:
In ectotherms, your body temperature depends primarily on external heat sources. The temperature of the ectotherms increases or decreases in conjunction with the temperature of their environment. Despite the fact that ectotherms produce some metabolic heat, they cannot increase their heat to maintain a specific internal temperature.
On the other hand, ectotherms regulate their body temperature, but seek sun, shade, etc. to search for environments whose temperatures compensate your needs.
