Term abiotic
Definition

Lifeless, relative to that which is not alive. Component, structure, formation, element or factor that is inert. In general, it refers to any physical and chemical factors of ecosystems which affect living organisms. Some of these factors include: sunlight, temperature, precipitation, wind, altitude, latitude, fire frequency and the nature of the soil. Abiotic factors determine the physical space inhabited by living organisms, and are the key inhibitors of growth and development of a population. For example, in aquatic ecosystems, the limiting abiotic factors are water currents, the concentration of dissolved nutrients and the amount of dissolved organic matter. 

The favorable combination of abiotic factors such as the availability of proper sunlight, rainfall and a moist and fertile soil, has always been the economic foundation of the Dominican Republic. The agricultural industry has developed thanks to the fact that 76% of the land in the North, Northeast, East, and in the heart of the country has a high content of organic matter and, therefore, is suitable for cultivation. The country has also become a mining powerhouse by taking advantage of the soil’s high mineral content. Gold, platinum, iron ore, rock salt, gypsum, marble, limestone, oil and nickel are abundant in Dominican soil.
