Name three adaptations of reptiles that enable them to live on land.

Reptiles have dry, tough skin covered in scales, which reduces water loss. Reptiles breathe using lungs; they do not exchange gases through their skin. Their kidneys also help prevent water loss by concentrating their urine. Young reptiles develop inside an amniotic egg, which is covered with membranes and a shell to prevent it from drying out.

Explanation:

Sample answer

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
