Detailed explanation-1: -Producers, such as green plants, are organisms that utilize solar or chemical energy to synthesize starch. All food chains must start with a producer. Producers, also known as autotrophs, make their own food. They make up the first level of every food chain.

Detailed explanation-2: -At the base of the pyramid are the producers, who use photosynthesis or chemosynthesis to make their own food. Herbivores or primary consumers, make up the second level.

Detailed explanation-3: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Detailed explanation-4: -Plants are producers. They make their own food, which creates energy for them to grow, reproduce and survive. Being able to make their own food makes them unique; they are the only living things on Earth that can make their own source of food energy. Of course, they require sun, water and air to thrive.

Detailed explanation-5: -The site of photosynthesis in plants is the chloroplast. This cell organelle is found in plant cells and contains chlorophyll, a green-coloured pigment.
