d mistletoe on the trees increases the reproduction rate of the trees.
e mistletoe on the trees increases the number of birds eating berries and spreading seeds from both plants.

Explanation:

In a mutualistic relationship, all parties benefit. Mistletoe gets water and nutrients from juniper trees, and birds feed on the berries which helps in seed - spreading for both plants. Evidence for this includes mistletoe getting resources from trees (A), and mistletoe increasing the reproduction rate of trees (D) as well as increasing the number of birds which help in seed - spreading (E).

Answer:

Part A: A. mutualistic
Part B: A. Mistletoe gets water and nutrients from the trees, D. Mistletoe on the trees increases the reproduction rate of trees, E. Mistletoe on the trees increases the number of birds eating berries and spreading seeds from both plants.
