In a food web, which organism is a primary producer?

Rabbit Grass Eagle Snake

Correct Answer:

Grass

Explanation:

Primary producers are organisms that make their own food using energy from the sun, turning light into chemical energy stored in sugars. Grass is a plant that does this through photosynthesis, so it sits at the base of the food web. The rabbit eats grass, making it a consumer that relies on producers for energy. Predators like the snake and the eagle obtain energy by eating other animals, not by producing their own food, so they’re higher up in the food web. Therefore, grass is the primary producer.
