ACCURATE ANSWERS. WELL
VERIFIED!!
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
Mark & recapture - CORRECT ANSWER-Capture, mark & release individuals.
Resample & record number of marked and unmarked individuals
Why is human population growing exponentially? - CORRECT ANSWER-
Resouces, medicine, sanitation, technology

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

Mark & recapture - CORRECT ANSWER -Capture, mark & release individuals.

Resample & record number of marked and unmarked individuals

Why is human population growing exponentially? - CORRECT ANSWER -

Resouces, medicine, sanitation, technology

Competitive exclusion principle - CORRECT ANSWER -species competing for

identical resources cannot exist

Niche partitioning - CORRECT ANSWER -niches appear to differ among

sympatric species

What happens when you remove a species from a community? - CORRECT

ANSWER -Diversity goes down

What do indirect effects do to a species? - CORRECT ANSWER -They can have

a massive effect on the community

biodiversity - CORRECT ANSWER -the variety of life in the world or in a

particular habitat or ecosystem

carrying capacity - CORRECT ANSWER -the number of people, other living

organisms, or crops that a region can support without environmental degradation

Coevolution - CORRECT ANSWER -reciprocal evolution of two or more species.

single species evolves in response to another group of species

diffuse coevolution - CORRECT ANSWER -a group of species evolves in

response to another group of species & vice versa

Phases of virulence - CORRECT ANSWER -• Pathogen either passes through

species without causing disease or kills too quickly to persist. Ex) Ebola

  • Pathogen becomes established but still too virulent to maximize its probability of transmission. Ex) HIV
  • Pathogen is well adapted to host; kills people but not before descendants leave & find new hosts. Ex) malaria & influenza

What factors should effect how fast virulence evolves? - CORRECT ANSWER -

Immune system of person infected, dense population, contact rate, life span

How is biodiversity dynamic? - CORRECT ANSWER -Species are constantly

changing

What causes adaptive radiation? - CORRECT ANSWER -colonization,

innovation, extinction

colonization - CORRECT ANSWER -Invasion of new regions promotes

diversification
