Are oak trees decomposers

No, oak trees are not decomposers; they are producers. As a type of tree, they generate their own energy through photosynthesis and provide habitat and food for various organisms. Decomposers, such as fungi and bacteria, break down dead organic matter, including fallen leaves and dead trees, recycling nutrients back into the ecosystem. Oak trees can contribute to this process when they die or shed leaves, but they do not perform decomposition themselves.
