Answer:
epiphytic roots
Explanation:
Epiphytic roots are those that live on other plants without parasitism. In this relationship, the epiphyte uses the other vegetable only as a support (phorophyte), removing no nutrients and, consequently, causing no harm to the species.
Epiphyte roots are estimated to represent about 10% of the total amount of vascular plants on the planet. This means that there are on average 29,000 plant species with this peculiar habit of life. These vegetables are mainly found in tropical rainforests and have almost no representatives in places with very low temperatures.
