Extreme habitats are regions of the earth that are either very cold or very hot. For animals and plants living in these habitats, the best survival strategy appears to be becoming very large (over 50 kg) or very small (under 15 kg). Why do you think this is?
- How can being large help an animal stay warmer in cold weather and cooler in hot weather?
- How can being small allow an animal to make use of soil and tree holes as habitats or microhabitats?
