-
According to allens rule what can be said about the size of the animals appendages in terms of latitude
when you get further away from the equator the appendages get shorter
-
What are the limits of tollerance
range of conditions under which a organism is able to function and survive
-
How is population growth calculated?
(birthrate+imigration)-(deathrate+emigration)
-
Why do population sizes fluctuate naturaly?
Because once you reach carrying capacity enviromental resistance causes it to fluctuate
-
Why did we look at mammal Skulls?
so we can learn the difference of teeth with the different diets
-
What are the differences between a rabbit skull and a coyote skull
Rabbit skulls have large incizers while coyotes have large canines
-
Why is carrying capacity important when talking about populations
if a population exceeds carrying capacity the food resources will die out
-
What is habitat fragmentation
when vegitation is cleared by human activity
-
What are habitat corridors?
a strip of land that aids the movement of species between disconected habitats
-
What are autotrophs
produces own food has the most atp
-
What are heterotrophs
organsims that rely on other organisms for food
-
What are decomposers
breaks down no longer living things
-
What is an indicator species?
Very frigile, lets us know when the habitat is failing
-
WHat is a Keystone species?
Keeps ecosystems stable, without it the habitiat will fail
-
What are the ways that organims survive the winter
Hibernation, dormancy, activeness, and migration

-
what do the arrows on the food web tell us
the way the energy is flowing
-
What is an owl pellet?
regurgitation of food that could not be digested
-
why do trees disapear in succsession
the reasources are limited causeing the weeker to die out
-
Why do trees appear in succsession
there is room for the trees to reproduce and take over
