Which organism depicted in this food web is a producer?From where do producers obtain their energy?

The producer is some kind of plant

Explanation:

Producers are plants, because plants produce their own food through photosynthesis. Producers obtain their energy from the sun, which they then use in photosynthesis. The equation for photosynthesis is below:

sunlight+water+carbon dioxide⇒oxygen+glucose

In every food web, plants are the producer. Producers obtain their energy from the sun.

Explanation:

Plants are the producers because they produces food for other organisms from the sun. The process in which food is produced is photosynthesis. In this process carbondioxide enters through small opening called stomata and water is absorbed by the plant from the soil. When these two substances combine in the presence of sunlight produces glucose and oxygen. Oxygen is released in the atmosphere and glucose is stored in different parts of plant.
