Final answer:
In a food chain, the producer is the organism that synthesizes its own food using energy from the sun. The correct answer for the producer in this food chain would be plant.
Step-by-step explanation:
In a food chain, the producer is the organism that synthesizes its own food using energy from the sun. It is usually a plant, such as a tree or algae, that undergoes photosynthesis to produce glucose and oxygen. This energy is then passed on to other organisms in the food chain.
For example, in a simple food chain, a plant like grass is the producer. It captures sunlight energy through photosynthesis and converts it into stored energy in the form of glucose. This energy is then consumed by herbivores like rabbits, which are then eaten by predators like foxes or birds.
So in the given options, the correct answer for the producer in a food chain would be plant (option B).
