Detailed explanation-1: -All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

Detailed explanation-2: -Green plants are the only living organisms that produce their own food. Light provides the energy to create a chemical reaction within specialized cells, called chloroplasts, in the leaves. Chlorophyll present in the chloroplasts captures light energy and uses it to produce simple sugars from carbon dioxide and water.

Detailed explanation-3: -Plants are called producers because they make – or produce – their own food. Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight.

Detailed explanation-4: -Plants make their own food through photosynthesis.

Detailed explanation-5: -Not all plants are producers (autotrophs). Some plants are parasitic in nature. These plants get their food from another living plant and are adapted to feed on these plants. Such parasitic plants are not producers but consumers (heterotrophs).
