The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata (singular = stoma). Normally stomata open when the light strikes the leaf in the morning and close during the night
Answer:
Photosynthetic autotroph
Explanation:
Plants, algae/seaweed and some bacteria can use photosynthesis to turn light energy, carbon dioxide and water into glucose and oxygen. The glucose, or sugar becomes the food for these organisms.
Since they can produce their own food, they are called producers, but they are also called autotrophs. "Auto" meaning self, and "troph" meaning nutrition. Therefore, the correct choice is: Photosynthetic autotroph.
Decomposers are those organisms that recycle matter in the ecosystem.
