Final answer:
The pea aphid is capable of producing its own food through photosynthesis by using chloroplasts to convert light energy into chemical energy and synthesize glucose from carbon dioxide and water.
Step-by-step explanation:
Photosynthesis is a process by which certain organisms, called photoautotrophs, convert light energy into chemical energy to produce their own food. One such organism that possesses this capability is the pea aphid (Acyrthosiphon pisum). The pea aphid contains chloroplasts in its cells, which enable it to perform photosynthesis. These chloroplasts contain chlorophyll, a pigment that absorbs light energy from the sun. The absorbed light is used to convert carbon dioxide and water into glucose, a form of stored energy, and release oxygen as a byproduct.
