The answer is fruit trees, birds/monkeys, tigers. Producers are the first level of the food chain. Plants are producers because they produce their own food. So, fruit trees will be at the beginning of the food chain. The next level belongs to 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, such as birds and monkey. Tigers are secondary consumers, and thus they are last on the food chain list.
