Not all plants do photosynthesis, the plants that don't, are called parasites, but is better known as holoparasitic plants. 20% of plants these days are classified as holoparasitic.
e.g plants at the bottom of the sea do not get much sunlight and nutrients so they get it from soil.
Plants that don't do photosynthesis have to get energy and nutrients from a autoptrophic host plant, but they cannot get nutrients unless they are directly attached to it by using their haustorium. 40% attach to the stem of it's host plant. 60% attach to it underground, as root-parasitic species. Though Fungi don't use them.
Fungi is also known as my mycoheterophytes. They connect to the tree that connects to the host plant that feeds the parasitic plant.
Another type of plant that don't use sunlight as it's main source is known as saprophyes. They get their name by obtaining energy from dead oraganic matter.
