All green plants and bacteria which can synthesize their food by photosynthesis come under the category of

Concept:-

• Green plants and bacteria which can synthesize their food by photosynthesis are called autotrophs.
• An autotroph uses photosynthesis under the category of procedures. Therefore Option 4 is Correct.
• Photoautotrophs include plants, algae, and cyanobacteria.
• Heterotrophs are organisms that depend on other animals for food.
• Chemoautrotrophs are organisms that synthesize sugars by taking energy from inorganic chemical compounds.

Explanation:

• The equation of photosynthesis is 6CO₂+6H₂0 -(sunlight)→ C₆H₁₂O₆+6O₂
• Photosynthesis takes place in leaves in the middle layer called the mesophyll.
• The exchange of gases occurs through stomata.
• Decomposers are organisms that break down dead and decaying organisms.
• Bacterias, mushrooms, and worms are examples of decomposers.
