Question

Which of the following is not a producer?

विकल्प

• Agaricus

• Ulothrix

• Riccia

• Dryopteris

Answer 1

Agaricus

Explanation:

Agaricus is a fungus and does not perform photosynthesis, so it is not a producer. Producers are green organisms that fix solar energy through photosynthesis, such as Ulothrix (a green alga), Riccia (a bryophyte), and Dryopteris (a fern), all of which are autotrophs that produce their own food. Agaricus, being a fungus, is a decomposer that relies on external organic material for nutrition, so it is not a producer.
