ASU BIO 182 Exam 3 questions with
verified solutions/passed
What is a resource? - correct answer ✔✔Any substance an organism requires to survive or reproduce.
Ex) food, water, mates shelter, nutrients, oxygen/co2
What factors determine prey choice? - correct answer ✔✔Energy content, encounter rate, handling
time, search cost
Profitability - correct answer ✔✔(energy / handling time)
animals = high profitability
fruits/veggies = low profitability
Why not grow to largest population size possible? - correct answer ✔✔• Many die before having chance
to reproduce
• All else being equal, early reproducers leave more decedents. Earlier you reproduce, the earlier your
children can reproduce
Energy budget - correct answer ✔✔Maintenance, production, activity
Why is reproduction costly? - correct answer ✔✔• Energy for mating, gametes, and parental care
• Exposure to predators & impaired locomotion
• Missed opportunity to feed & thermoregulate
population - correct answer ✔✔group of species living in a given area
Sampling - correct answer ✔✔count individuals in a few small areas & extrapolate for the entire area
