evolution of a nonoxious species to resemble a poisonous or inedible species.
wavelengths of light between 400 and 700 nm that photosynthetic organisms use as a source of energy
heterotrophic organism that eats plants
organism that consumes flesh; approx. synon. with predator
an organism that uses carbon dioxide as a carbon source and light as an energy source to synthesize organic compounds
total co2 uptake during photosynthesis minus the co2 produced by the plant's or alga's own respiration
process that maximizes or minimizes some quantity
organisms that feed on nonliving organic matter, usually on the remains of plants
autotrophs that use inorganic molecules as a source of carbon and energy
level of light intensity, often measured as photon flux density
number of photons of light striking a square meter surface each second
co2 is fixed in mesophyll cells by combining it with phosphoenol pyruvate, or PEP to produce a 4 carbon acid; generally more drought tolerant than c3
prokaryotes distinguished from bacteria on the basis of structural, physiological, and other biological features
increase in animal feeding rate, which eventually levels off, that occurs in response to an increase in food availability
Structure which surrounds leaf veins of c4 plants, made up of cells where 4 carbon acids produced during carbon fixation are broken down to 3 carbon acids and co2
a photosynthetic pathway largely limited to succulent plants in arid and semiarid environments, in which carbon fixation takes place at night when lower temperatures reduce the rat
an organism that can synthesize organic molecules using inorganic molecules and energy from either sunlight or from inorganic molecules such as hydrogen sulfide
an organism that uses organic molecules both as a source of carbon and a source of energy
a photosynthetic pathway which the product is PGA, a 3 carbon acid
theory that attempts to model how organisms feed as an optimizing porcess, a process that maximizes or minimizes some quantity, such as energy intake or predation risk
the enzyme that catalyzes the initial reaction in photosynthesis that combines co2 and ribulose biphosphate
comimicry among several species of noxious organisms
