• Carbon dioxide (CO₂) : Absorbed from the atmosphere through small openings called stomata in the leaves.
• Water (H₂O) : Absorbed by the roots from the soil and transported to the leaves.
• Light : Solar energy is captured by chlorophyll to drive the process of photosynthesis.
• Chlorophyll : The green pigment in chloroplasts that absorbs light energy to carry out photosynthesis.

• Mucus : Protects the stomach lining from being damaged by the acidic environment.
• Pepsin and Rennin : Enzymes that help in the digestion of proteins.
• Hydrochloric acid (HCl) : Creates an acidic environment, which aids in protein digestion and kills harmful bacteria.

1. Dilute Hydrochloric Acid (HCl) : Helps create an acidic environment for digestion.
2. Mucus : Protects the stomach lining from the acidic contents.
3. Protein Digesting Enzymes (Rennin and Pepsin) : Aid in breaking down proteins into simpler substances.

1. Amoeba ingests food by using its finger-like projections called pseudopodia.
2. The food is engulfed with a little surrounding water to form a food vacuole inside the Amoeba. The food is digested inside food vacuole by digestive enzymes.
3. Food is absorbed directly into the cytoplasm of Amoeba by diffusion.
4. Food is used to obtain energy and growth of Amoeba.
5. When considerable amount of undigested food collects inside Amoeba then its cell membrane ruptures at any place to throw out this undigested food.

1. Engulfing Food: When a food particle comes close to Amoeba, it extends its temporary finger-like projections called pseudopodia around the food particle.
2. Formation of Food Vacuole: The food particle is engulfed along with some surrounding water to form a food vacuole inside the Amoeba.
3. Digestion: The food is digested inside the food vacuole by digestive enzymes .
4. Absorption: The digested nutrients are absorbed directly into the cytoplasm of the Amoeba by diffusion .
5. Utilization of Nutrients: Part of the absorbed food is used to obtain energy, while the remaining nutrients are utilized for the growth of Amoeba.
6. Egestion: When a significant amount of undigested food accumulates inside the Amoeba, the cell membrane ruptures at any point, allowing the expulsion of the undigested food. This process is known as egestion .
