Is Rafflesia a parasite?

How does a bird get rid of mistletoe?
Birds are immune to toxic mistletoe berries and act as agents to disseminate the seeds. After birds digest the berries, they excrete the seeds, which are coated with a sticky substance that adheres them to trees. Rootlike structures called haustoria penetrate the tree bark and begin growing inside the branches.
How many species of mistletoe are there in Australia?
Subtropical and tropical climates have markedly more mistletoe species; Australia has 85, of which 71 are in Loranthaceae, and 14 in Santalaceae. Mistletoe species grow on a wide range of host trees, some of which experience side effects including reduced growth, stunting, and loss of infested outer branches.
Why is mistletoe considered a partial parasite?
Mistletoe is considered to be a partial parasite or semi-parasite because it manufactures all of its carbohydrates through photosynthesis in its green leaves, but it depends on its host tree for water, minerals, and protein.
