You have an ecosystem with the following organisms: birds, fruit trees, tigers, and monkeys. which list would best describe the food chain?

The priority list will be like this

In an ecosystem, producers are the first level of the food chain. And we know that plants are producers because they produce their own food. So, fruit trees will be at the beginning of the food chain. After producers comes the primary consumers. Primary consumers are animals that feed on producers. Both birds and monkeys feed on fruit trees, so they are the next in line after fruit trees. Finally, secondary consumers eat primary consumers. As tigers eat animals i.e monkeys etc so they are secondary consumers, and thus they are last on the food chain list.
