grasshopper
berries
plantain
the rabbit population would increase.
the titmouse (bird) population would decrease.
the butterfly population would increase
nothing would change.

Explanation:

Berries are a food source for the greenfly. If berries disappear, greenfly population may decline due to lack of food. Butterflies also rely on plants for food and habitat, and a change in the plant - based food chain can affect them. Titmice eat insects like grasshoppers and other small invertebrates that are part of the food chain starting from berries. With the disappearance of berries, the food chain is disrupted, and the titmouse population may decrease as their prey's population is affected. Rabbits do not directly rely on berries, and the butterfly population is likely to decrease rather than increase due to the disruption of the plant - based food source.

Answer:

The titmouse (bird) population would decrease.
