factors that a species needs to survive, stay
healthy, and reproduce. (role of the organism)
Answer 1 – 20
• Niche
Question 1 - 30
• The principle that states when two species are
competing for the same resources, one
species will be better suited to the niche, and
the other species will be pushed into another
niche or become extinct
Answer 1 – 30

Question 2 - 20
• A close ecological relationship between two or
more organisms of different species that live
in direct contact with one another
Answer 2 – 20
• Symbiosis
Question 2 - 30
• The type of symbiotic relationship in which
both organisms benefit from one another
Answer 2 – 30
• Mutualism
Question 2 - 40
• The type of symbiotic relationship in which
one organism benefits and the other is
unaffected
Answer 2 – 40

Question 3 - 20
• The way in which individuals of a population
are spread in an area or a volume
Answer 3 – 20
• Population dispersion
Question 3 - 30
• The pattern of dispersion in which individuals
may live close together in groups in order to
facilitate mating, gain protection, or access to
food resources
Answer 3 – 30

surviving members over time from a
measured set of births

begins with a period of slow growth followed
by a brief period of exponential growth
followed by leveling off at the carrying
capacity
Answer 4 – 30

number of individuals in a given area
Answer 4 – 50
• Density-dependent limiting factors
Question 5 - 10
• The sequence of biotic changes that
regenerate a damaged community or create a
community in a previously uninhabited area
Answer 5 – 10
• Succession
Question 5 - 20
• The establishment and development of an
ecosystem in an area that was previously
uninhabited
Answer 5 – 20
