▶ Organisms. Answer: individual living entities that survive and
reproduce as a unit
▶ population. Answer: consists of all the individuals of a species living
within a specific area
▶ populations can interact with each other in positive and negative
ways, and together they form a. Answer: community
▶ ecosystem. Answer: consists of all the living things in a particular
area together with the abiotic, or nonliving, parts of that environment
▶ biosphere. Answer: the collection of all ecosystems on Earth
▶ emergent properties. Answer: characteristics of a system that do not
appear in any one of its component parts alone, but that appear when all
parts are combined.
,▶ Biome. Answer: Areas of the earth with similar characteristics of
living and nonliving things

due to mutations and adaptations. Answer: Evolution: ancestry and/or
adaptation by natural selection
,▶ Ordered parts of biological system. Answer: Organization

considered. Answer: a nutrient
▶ When an organism releases matter, the excreted matter is considered.
Answer: waste
▶ Waste. Answer: Urine, feces, exhaled breath
▶ Reproduction. Answer: occurs when an individual organism passes on
its genetic information to a newly independent organism, or offspring
▶ Energy. Answer: the capacity to do work or to make a change in the
location, temperature, or structure of matter.
▶ chemical potential energy. Answer: what the substance can do if it is
put through a chemical reaction, like burning, that will release its stored
energy
