What type of organism is Mistletoe, and how does it affect trees?

Mistletoe is classified as a parasitic plant, which makes it distinct from other types of organisms. It attaches itself to the branches of trees and shrubs, drawing nutrients and water from its host plant. This relationship can weaken the host tree over time, as the mistletoe competes for essential resources necessary for the tree's health and growth.

Unlike decomposers that break down organic matter to enrich the soil, or symbiotic organisms that provide mutual benefits, mistletoe relies entirely on its host for sustenance. Additionally, mistletoe is not an insect, so it does not play a role in pollination. Instead, its parasitic nature can lead to stress in the host tree and may ultimately contribute to decline or even death if the infestation is severe. This understanding highlights the negative impact mistletoe can have on tree health, supporting the accuracy of the selected answer.
