Answer:
Runoff is nothing more than water "running off" the land surface.
<h3>Explenation:</h3>
Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
Gause's Competitive Exclusion Principle
The 'competitive exclusion principle' (CEP) states that two species with identical niches cannot coexist indefinitely. ... Gause helped propel ecology by his approach of experimentally testing mathematical models, and his unifying the concept of the niche with resource competition.
Mycorrhizae, specialized symbiotic associations between the roots of plants and fungi, are characteristic of about 90% of all plants.
Mycorrhizal fungi are a symbiotic combination of fungi and plants. The term mycorrhiza refers to the role of fungi in a plant's rhizome, its root system. Mycorrhizae play an important role in plant nutrition, soil biology, and soil chemistry.
In mycorrhizal organization, the fungus resides in the root tissues of the host plant, either intracellularly as in arbuscular mycorrhizal fungi (AMF or AM), or extracellularly as in extrinsic fungi.
The association is sometimes reciprocal. In some species or in specific cases, mycorrhizal fungi may have a parasitic association with the host plant.
Mycorrhizae are generally divided into ectomycorrhizae and endomycorrhizae. These two types are distinguished by the fact that mycelium of mycorrhizal fungi does not penetrate individual root cells while mycelium of endophytic fungi penetrates the cell wall and penetrates the cell membrane.
