<span>As per excerpts, Water covers 75 percent of Earth and 97 percent of water on Earth is salt water, meaning only 3 percent of water is available as fresh water. Based on this information, 3% of 75% of the water on earth is available as fresh water or 2.25%. Since most of the water is said to be locked up in solid glaciers and polar ice caps, the amount of water on the planet that is available for animals to drink is lesser than 2.25% so the best approximation is 1 percent.</span>

Endothermic animals are able to generate their own warmth, however ectothermic animals can not.
On a hot summers day, endothermic animals will not need to rely on the sun's heat as they can regulate their body temperature on their own.
Ectothermic animals will most likely respond to this environmental change by sitting out in the sun to absorb the sun's warmth - as they dependant on this heat.
