In what habitat are most parasites?

Most parasites live in the organismic habitat. This is primarily due to their parasitic way of life, which means the dependence of vital processes on other animals, plants, etc. Despite this, many parasitic organisms can be found in the soil and in the ground-air and in the aquatic habitat, when part of it is immersed in the organism of the symbiont, and part of it communicates with the external environment: tinder fungus, orchids, wasp insect, etc.
