All __ use photosynthesis to create their food, or energy in the presence of __ An important component in photosynthesis is __ the pigment that gives leaves their green color. Photosynthesis occurs only in __ leaves.

## Step 1<br />The first blank in the sentence is asking for the type of organisms that use photosynthesis to create their food. Photosynthesis is a process used by plants, algae, and certain bacteria to convert light energy, usually from the sun, into chemical energy that can be later released to fuel the organisms' activities. This process is unique to these organisms, hence the answer is "plants".<br /><br />## Step 2<br />The second blank in the sentence is asking for the condition that photosynthesis requires. Photosynthesis requires light to occur. The light energy is captured by the chlorophyll in the plant cells and used to convert carbon dioxide and water into glucose and oxygen. Therefore, the answer is "light".<br /><br />## Step 3<br />The third blank in the sentence is asking for the name of the pigment that gives leaves their green color. This pigment is called "chlorophyll". Chlorophyll is the molecule in plants that absorbs light energy for photosynthesis. It is the reason why leaves appear green to our eyes.<br /><br />## Step 4<br />The fourth blank in the sentence is asking for the location where photosynthesis occurs in a plant. Photosynthesis primarily occurs in the leaves of a plant. The leaves contain chloroplasts, which are the organelles where photosynthesis takes place. The leaves are the main site of photosynthesis in most plants because they contain the highest concentration of chloroplasts.
