Level

Level

Producers
The sun
O Level B
O Level D

Answer:

The answer is the sun.

Explanation:

Level a represents the producers which you can tell, by their name, that they make their food. Producers are mainly comprised of the plants of our world. They get their energy from the sun and through photosynthesis, they turn it into energy.

By the way, B would be primary consumers which are the herbivores, C are the secondary consumers which include us people, and D are the decomposers, which include worms.

Level A represents the producers which make their own food and are mainly comprised of the plants of our world. They gain energy from the sun and through the process of photosynthesis.

The energy for use by organisms in level A originally comes from sun. Thus the correct option is A.

The process through which green plants and some other organisms use sunlight to make foods from carbon dioxide and water. Photosynthesis in plants generally involves the green colour pigment chlorophyll and generates oxygen as a byproduct.

Whereas, B would be primary consumers which are the herbivores, C are the secondary consumers that include omnivorous, and D are the decomposers, which include worms.
