Why animals depend upon plants for food? |
Answer» Animal cells do not have chloroplasts. Chloroplast trap the energy from sunlight. It converts solar energy to chemical energy which takes place during photosynthesis. During the process of photosynthesis food materials are formed. Due to lack of chloroplasts animals are unable to prepare their own food. So, animals depend on plants for food. |
