Detailed explanation-1: -Plants are autotrophs and convert the solar energy into food by photosynthesis hence they form the first trophic level of a food chain. Hence plants are called primary producers.

Detailed explanation-2: -Chloroplast traps solar energy during photosynthesis in plants. It has a green-colored pigment called chlorophyll which helps in the absorption of sunlight. Chloroplast helps in photosynthesis by converting solar energy into chemical energy.

Detailed explanation-3: -Encyclopedic entry. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.

Detailed explanation-4: -For example, plants obtain energy from sunlight and turn it into nutrients that can be eaten and used for energy by animals such as a caterpillar. The best-known and most common primary producers harness solar energy through the process of photosynthesis.

Detailed explanation-5: -Producers, also known as autotrophs, make their own food and do not depend on any other organism for nutrition. Most autotrophs use a process called photosynthesis to create food (a nutrient called glucose) from sunlight, carbon dioxide, and water.
