A
Consumers are eaten by a variety of producers.
B
Producers convert light energy into chemical energy.
C
Producers are larger than consumers.
D
Producers are found in fewer numbers than consumers
Explanation: 

Detailed explanation-1: -Every food chain starts with producers because only plants are capable of changing light energy into chemical energy, which is then used by both plants and other consumers.

Detailed explanation-2: -Explanation: Plants make up the bottom trophic level: the producers. This is because plants produce energy through photosynthesis. They do not have to eat other organisms to obtain energy, they make their own using carbon dioxide, water and sunlight.

Detailed explanation-3: -These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients.

Detailed explanation-4: -Producers are autotrophs, or organisms that produce their own food. Plants and algae are examples of producers. They are at the bottom of the food chain because they are eaten by other organisms, and they don’t need to eat for energy.

Detailed explanation-5: -Food Chains Plants make their own food through a process called photosynthesis. Using the energy from the sun, water and carbon dioxide from the atmosphere and nutrients, they chemically make their own food. Since they make or produce their own food they are called producers.
