Answer:
With increase of deer, there will be a decrease of producers.
Step-by-step explanation:
Increasing of deer populations means decreasing of producers. As more and more deers are eating plants, the producer population will decrease. Thus, the producer population are in demand and deers will eventually need to fight for food with other deers–– this is known as competition, which is a biotic factor. An abiotic factor can be lack of oxygen once the producer population has been decreased due to the increase deer population.
