What organism is the producer in this food web Pine rabbit squirrel or fox?

In a food web, the producer is typically a plant or an organism that creates its own food through photosynthesis. In this case, neither the pine, rabbit, squirrel, nor fox is a producer, as they are all consumers in the food web. However, if you meant to refer to the pine tree, then it would be the producer, while the rabbit and squirrel would be primary consumers, and the fox would be a secondary consumer.
