Answer: spider
Step-by-step explanation:
Spiders are consumers, not producers, but they occupy a relatively low trophic level because they primarily eat insects and other small invertebrates. Deer, lions, hawks, and snakes are all higher on the food chain because they eat other animals, including herbivores like deer and carnivores like lions and hawks. Therefore, a spider occupies the lowest trophic level among the organisms listed in the question.
