Industry:Biology
The even distribution of individuals of a species. Of two groups of plants, roughly 50 individuals in each group is fairly even; 2 in one group and 50 in the other would be uneven. See Richness.
Industry:Biology
A salt or ester (acid-alcohol product) of nitric acid; in soil, used by plants for building amino acids and proteins. Artificially manufactured nitrates are used in fertilizers and explosives.
Industry:Biology
Sudden depopulation as a result of resource depletion. A crash can often be seen a long way off in communities on a direct course to disaster through overuse of food and other vital supplies.
Industry:Biology
Unprocessed carbon compounds added to an aquatic environment. Example: straw or leaves blown into a pond. Microorganisms eventually break it down into FPOM (Fine Particulate Organic Matter).
Industry:Biology
The maximum poplation an ecosystem can support of a given species. An ongoing debate focuses on whether the Earth's carrying capacity for humans has already been exceeded or shortly will be.
Industry:Biology
Segments cut from parent plants for growing elsewhere. Cuttings grow best from sunside shoots or branches with two nodes each. They are planted with the top bud just clear of the soil.
Industry:Biology
The accumulation of marine sediments at the edges of a continent, building up in some cases into entire coastal mountain ranges. See Plate Tectonics for more about what causes accretion.
Industry:Biology
A type of limestone sedimented together from the skeletons and shells of marine microorganisms; it resists erosion but is porous, often gathering a lot of water beneath its formations.
Industry:Biology
Similarities that appear independently in more than one type of organism. (Animals that live in similar surroundings often resemble each other, for instance. ) Contrast with Homology.
