Question

Which of the following is a primary producer in a pond ecosystem?

Options

• Algae

• Fungi

• Virus

• Bacteria

Answer 1

Algae

Explanation:

Algae are primary producers in a pond ecosystem because they are autotrophic green plants that perform photosynthesis, fixing solar energy into organic food. They form the base of the food chain by producing energy that is then passed on to consumers and decomposers. Algae and other green plants, such as phytoplankton, are key producers in ponds, sustaining the entire ecosystem’s energy flow.
