I need to come up with a really good hypotheses for Why do certain animals eat more at certain temperatures than others or than they do at other temperatures? I just don't know what a good hypotheses is but here are some examples of bad ones:

Question

An organism's metabolism is affected by temperature.
-It doesn't offer a cause. It's too general - it leads to so broad a prediction that experimental results can be misleading.

Mice will have a lower metabolic rate than crickets.
-It doesn't take the question into consideration. It is a prediction rather than a hypothesis. Doesn't take into consideration information regarding these animal's metabolism and pattern of temperature conformity as discussed in lecture or in the textbook.

Mice will eat more when they are hot.
-This cannot be tested in this short a lab period (requires days). It doesn't take the question into consideration. It is a prediction rather than a hypothesis.

If the temperature decreases then the metabolic rate changes.
-Once again, this hypothesis is too general, and does not offer a cause for the change.
