Explanation:
An enhanced amount of light from Sun will cause the plants to have enhanced photosynthesis. Photosynthesis can be described as a process by which plants use light energy from the sun to convert carbon dioxide and water into sugar (food) and oxygen.
In animals, enhanced amount of light from the sun will cause sweating and vasodilation. 
 The process of photosynthesis won't occur in animals and the process of sweating won't occur in plants.
