biodiversity – biological diversity; the diversity of species, genes, and/or ecosystems.
bipedal – walking on two legs.
carrying capacity – the number of a given species that an area can support without impairing its ability to continue supporting that population.
DNA – deoxyribonucleic acid. Large molecules in cells that carry the genetic information in living organisms.
ecosystem – a community of different species interacting with one another and with the chemical and physical factors making up their non-living environment.
ethics – a system of moral principles.
fertilizer – substance that adds organic or inorganic nutrients to soil and improves its ability to grow crops, trees, or other vegetation.
flux – the rate of flow of particles, fluid, or energy.
gene – coded units of information (segments of DNA molecules) about specific traits that are passed on from parents to offspring during reproduction. /p>
Ha – hectare, equivalent to 10,000 m2 or 2.471 acres.
habitat – place or type of place where an organism or a population of organisms lives.
hypothesis – educated guess as to the outcome of an experiment.
kg – kilogram, equivalent to 1000 grams
Mt – metric tons
nutrient – any atom, ion, or molecule an organism needs to live, grow, or reproduce.
overpopulation – when long term carrying capacity is being degraded by its current occupants.
parameter – a constant aspect of an environment that determines a specific part of that environment but not its general nature.
photosynthesis – the process by which plants use sunlight to combine carbon dioxide and water to produce carbohydrates and oxygen.
phytoplankton – small drifting plants, mostly algae, that live in aquatic systems.
population – group of individual organisms of the same species living within a particular area.
primary productivity – the rate at which plants photosynthesize
religion – a specific fundamental set of beliefs and practices generally agreed upon by a number of persons or sects.
respiration – process that occurs in the cells of living organisms in which sugars or carbohydrates combine with oxygen to produce carbon dioxide and water and energy.
trait – a distinguishing characteristic or quality.
transgenic – having a gene(s) from another organisms through the biotechnological transfer of DNA.
treatment – an experimental manipulation of the immediate environment surrounding an organism.
yr – year
zero population growth – the state of equilibrium reached when birth and death rates are the same.
