Ecology (BIOL 310) Final Exam With
Actual Solution (2025)!!


Homeostasis - Answers Biological mechanisms that regulate the
levels of certain things such as heat, water, nutrients...

Work within limits



Shelford's law of tolerance - Answers There is a range of
environmental conditions within which organisms can survive.

Organisms distribution will be across the variety of environments that it can
tolerate.

Organisms will be most abundant in the center of the range of tolerable
environmental conditions, with less abundance leaving the ideal (median)



Leibig's Law of the minimum - Answers Least available necessary
nutrient will restrict plant/algal growth, Limiting Nutrient. Adding more will
allow for increase growth until another nutrient becomes limiting factor.

Be familiar with bell-shaped curve.



Blackman's law of "too much of a good thing" - Answers Optimum is
somewhere in the middle, bell-shaped curve

, Q/As
Describe how air masses rise near the equator, what happens to the water
vapor carried as related to dew pt and adiabatic cooling and then where the
air masses descend. - Answers Air rises at equator because it gets
12 hrs of direct sunlight all year.



As air rises, pressure and temperature decrease (adiabatic cooling)



Saturation VP drops as the air rises and when it is equal to Current VP
(Dewpoint) water vapor condenses to form clouds, rain falls on equator



Dry air spreads towards poles and falls at 30 degrees N/S of equator, heats
as it falls --> deserts



Coriolis Effect - Answers The rotation of the earth causes deflection
of air

Northern Hemisphere= to the right (clockwise)

Southern Hemisphere= to the left (counterclockwise)



Relate the ecosystems to the amount of moisture in the air masses as the
air masses rise and where they descend (i.e. ecosystems at the equator
and 30N and S latitude) - Answers Equator gets direct sunlight all
year long.

Water at equator are warmed leading to evaporation

As air rises it cools adiabatically, when it reaches dewpoint it releases
moisture forming clouds.

Rain falls heavily at equator

, Q/As
Now significantly dryer, cool air moves north and south

This cool dense air fall to surface around 30 latitudes

As it falls it heats adiabatically, creating warm climate at these latitudes.

Also since the air now has low Current Vapor Pressure it doesn't reach
dewpoint and forms no clouds-->no rain



Use data to determine which mechanism is the likely agent (genetic drift,
natural selection or gene flow) causing changes in gene frequencies (water
snake example). - Answers Look at the example.



Calculate refuge size for a given organism using population genetic and
ecological information (water snake example). - Answers Do the
calculations yourself or you won't fully understand it.



Crude Density - Answers Population size/area sampled



Ecological Density - Answers Population size/habitable area



Age Pyramids: be able to interpret age pyramid for a growing, stationary -
Answers



Uniform Dispersion Pattern - Answers Evenly spaced

For animals can be territorial (defended against others)

For Plants can be caused by limited resources resources (a patch of earth
can only support so many plants nutrient-wise)
