Answer
'Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration.'
Explanation
## Step 1Photosynthesis and cellular respiration are two fundamental biological processes. Photosynthesis is a process used by plants and other organisms to convert light energy, typically from the sun, into chemical energy in the form of glucose. This process is crucial for life on Earth, as it provides the primary energy source for nearly all organisms. In photosynthesis, solar energy is absorbed by chlorophyll and used to convert carbon dioxide and water into glucose and oxygen.## Step 2Cellular respiration, on the other hand, is a process that occurs in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. The most common nutrient used in cellular respiration is glucose, which is derived from the food organisms eat or, in the case of plants, glucose produced in photosynthesis. During cellular respiration, glucose is broken down, and the energy released is used to produce ATP, the energy currency of the cell.## Step 3The two statements to be evaluated are:1. "Solar energy is needed for photosynthesis, and chemical energy in the form of glucose is needed for cellular respiration."2. "Chemical energy in the form of glucose is needed for photosynthesis, and solar energy is needed for cellular respiration."## Step 4The first statement correctly describes the energy needs for both photosynthesis and cellular respiration. Photosynthesis requires solar energy to drive the synthesis of glucose, while cellular respiration uses the chemical energy stored in glucose to produce ATP. ## Step 5The second statement is incorrect as it reverses the energy sources for the two processes. Photosynthesis, not cellular respiration, requires solar energy, and cellular respiration, not photosynthesis, primarily uses glucose.
