aquaculture Production of food from aquatic habitats.
crop rotation A series of different crops planted successively in the same field, with the field occasionally left fallow or with a cover crop.
genetically modified crops Crop species modified by genetic engineering to produce higher crop yields and increase resistance to drought, cold, heat, toxins, plant pests, and disease.
green revolution Name attached to post-WWII agricultural programs that have led to the development of new strains of crops with higher yield,better resistance to disease, or better ability to grow under poor conditions
limiting factor The single requirement for growth available in the least supply in comparison to the need of an organism.Originally applied to crops but now often applied to any species.
macronutrients Elements required in large amounts by living things. These include the big six-carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur
