Fish are Cooler Than Humans

Describing 2–3 different strategies that organisms employ to obtain free energy for cell processes (e.g., different metabolic rates, physiological changes, variations in reproductive and offspring-rearing strategies).

1. Regulation of body temperature: Tuna fish are able to regulate their internal body temperature better than some other sea life. This allows them to swim in a varying range of temperatures. This mobility gives them access to a greater amount of resources.

2. Consumption of other organisms: We humans obtain practically ALL of our energy through eating plants and other animals. Because we are unable to photosynthesize, or hunt stealthily for our food, we have had to improvise and become a species that farms and raises animals for food.
