BIO 182 EXAM 3 2026 BIODIVERSITY DRILL
PACK ANSWER SHEET
◉ Biotic Factor.
Answer: Living aspects affect organisms
◉ Fundamental Niche.
Answer: the range of conditions that a organisms can handle (yellow
area)
◉ Realized Niche.
Answer: The niche species actually lives (green area)
◉ The niche of a species....
Answer: Limits its geographic distribution
◉ Topt.
Answer: Optimal temperatures for species
◉ CTmin.
,Answer: (Critical Temperature MIN) The lowest temperature a
species can go (see right of the image)
◉ CTmax.
Answer: (Critical Temperature MAX) The highest temperature a
species can go (see left of the image)
◉ Characteristics of a population.
Answer: Size, distribution, density, dispersion, age range, and
structure & life history
◉ Transects.
Answer: Measuring a section of an ecosystem to measure a certain
population of wildelife
◉ Mark and recapture.
Answer: Technique used to determine population size in
populations. Used by marking animals and tracking them.
◉ Photo traps.
Answer: The technique of using a blended-in camera to track certain
populations of wildlife
, ◉ Aerial surveys.
Answer: Tracking wildlife with a fixed wing air craft or helicopter.
AKA tracking services in the air.
◉ Radio tagging.
Answer: Putting a radio transmitter onto an animal (best used for
tracking birds)
◉ Visual census.
Answer: A way to track animals by looking at them visually (best
used for swimming/underwater wildlife)
◉ Mark and recapture formula.
Answer: (# first catch [n1]) * (# second catch [n2])/ (# of tagged
caught [m2]) = N
◉ Contributors to the increase and decrease of population.
Answer: Immigration, Emigration, Births, & Deaths
◉ Population changes formula.
Answer: FIRST: Change in species (ΔN) = (N1 [final population
observation] - N0 [initial population observation]) OR (Births-
Deaths) + (Immigration-Emigration)
