Nutrient-poor environments, often referred to as oligotrophic environments, are ecosystems characterized by a scarcity of essential nutrients. These nutrients, such as nitrogen, phosphorus, and potassium, are vital for the growth and reproduction of most organisms. In these settings, the limited availability of these elements restricts the biomass and productivity of the ecosystem.

Such environments can be found in various forms. Aquatic examples include deep, clear lakes and oceans far from terrestrial runoff, where the water column has low concentrations of dissolved nutrients. Terrestrial examples include many sandy soils, exposed rock faces, and high-altitude or arctic regions where decomposition rates are slow and nutrient cycling is limited.

Organisms that inhabit nutrient-poor environments have evolved specific adaptations to survive and thrive. These often include slow growth rates, efficient nutrient uptake mechanisms, and strategies to conserve nutrients. For instance, plants in these conditions may have extensive root systems to capture scarce resources or form symbiotic relationships with mycorrhizal fungi. In aquatic systems, phytoplankton may possess specialized enzymes to utilize low concentrations of nutrients. The biodiversity in these environments can sometimes be surprisingly high, as the selective pressure favors species with unique adaptations, leading to specialized niches.
