1.Explain the energetic constraints that prohibit prokaryotes from getting larger than they are. Be sure to explain the implications of the energy canyon for the evolution of eukaryotes.

Space constraints.

Explanation:

Space constraints are the energetic constraints that prevent prokaryotes from getting larger than their limit. Space constraints control the sizes of both the largest and smallest bacteria. Bacteria can't shrink more than they have already because there is not enough space left for DNA and necessary proteins. In the same way, the prokaryotes can't increase in size beyond their limit due to space constraints.

a. by using fur or clothes to trap heat energy near the body
