Plant ecology a single growth-limiting resource, perhaps for light in agricultural systems with sufficient water and nutrients, or in dense stands of marsh vegetation, but in many natural ecosystems plants may be colimited by several resources, e.g. light, phosphorus and nitrogen at the same time. Therefore, there are many details that remain to be uncovered, particularly the kinds of competition that arise in natural plant communities, the specific resource(s), the relative importance of different resources, and the role of other factors like stress or disturbance in regulating the importance of competition. Mutualism is defined as an interaction "between two species or individuals
Artificial nails fitted properly, artificial nails are usually not problematic. However, long term use and poorly fitted nails can seriously damage the nail bed and hamper natural nail growth. The most common problem associated with artificial nails is a fungal infection that may develop between the false and natural nail. When artificial nails are applied to the natural nail surface, minor types of trauma to the artificial nails which can happen from something as harmless as scraping a nail against a firm surface can cause separation of the nail from its nail bed. This allows bacteria and fungus to potentially enter the
