Question	Answer
nonvascular plant	plant that lacks vascular tissue consisting of tubes and associated cells, which transport water and nutrients throughout the plant; lacking xylem and phloem
placental	provides for the nourishment of the fetus and the elimination of its waste products.
carbon cycle	processes, including photosynthesis, decomposition, and respiration, by which carbon as a component of various compounds cycles
carnivore	An animal that only eats meat.
carrying capacity	In ecology, the number of individuals of a particular species that a region can sustain indefinitely
commensalism	Symbiotic relationship between two organisms. when one organism benefits and one is unaffected.
competition	Two or more organisms competing for a resource

decomposers	An organism that gets energy from breaking down dead organisms or wastes
development	progression from a simpler or lower to a more advanced, mature, or complex form or stage
energy pyramid	A model to show the flow of energy through the food chain. Less energy is available at each level as you move toward the top.
energy transfer	flows from sun to autotrophs, and later transferred to organisms, which feed on autotrophs and become prey for tertiary consumers.
