Animal cells are not capable of producing their own food because they lack which organelle? vacuole chloroplast cell wall

Option B, Chloroplast

Explanation:

Plants cell have chloroplast which has green pigment known as chlorophyll. A plant photosynthesize because of this green pigment only. Chlorophyll is responsible for capturing sunlight and carbon dioxide from atmosphere and converting it into usable chemical energy such as glucose along with release of oxygen. Glucose acts as food source not only for plants but several other dependent organisms.

An animal cell do not has this chloroplast and hence unlike plant it is not able to produce its food.

Option B is correct

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).
