This is a symbiotic relationship. The mycorrhiza is harbored I the roots of the orchids. The fungi nitrify the soil around the plant. Therefore, the fungi make nitrates (which are critical for the growth of the plant) available to the plant. The fungi, on the other hand, are assisted in breaking down of large carbon polymers by the orchids because the plant’s enzyme is more powerful than those of the fungi.
If the presence or absence of a factor limits the growth of the ecosystems elements, it is called a limiting factor . There are several abiotic factors that limit ecosystem growth, including temperature, precipitation, sunlight, soil configuration, and soil nutrients
