Biology final part 2
what is a population?
A group of interacting species in a habitat
What is a Community?
Groups of interacting populations in a given habitat
What is a ecosystem?
Given area with interacting biotic and abiotic factors
What is Biodiversity
Number of different types of organisms that live in an area, greater when you get closer to the equator
What is a climax community
Everything is at carring cappacity tipicaly oldest community very stable
What is Reasource Partitioning
division of reasources (owl hunts at night, hawk hunts during the day)
What are two types of vascular tissue
Strems and roots
What are diciduous trees?
have broad leaves that shed in the fall, flowers
What is a coniferous tree?
Cone bearing, has needles that stay on year round
discribe a freshwater biome
effected by temature sunlight and oxygen, ponds lakes and rivers
What is a marine biome
Vary according to amount of sunlight degree of water temp and water movement, very high biodiversity
What is a temprate rainforest
Two far north to have year round warmness 300cm of rain
What is a Boreal Forest (taiga)
Cold harsh climate mostly carniforus trees low precipitation
What is a Gymnosperm
naked seed (carniforus trees)
What is a angiosperm
What is perma Frost?
frozen year round never thaws
According to bermans rule what is said about an animals body size in terms of latitude
When you get further away from the equator the bodys get more shperical
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?
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 is wisconsin state bird, animal and fish
Robin, badger, and muskee
What is the kingdom protista?
Group of eukaryotes both unicellular and muliticellular, autotrophs and heterotrophs
What is the kingdom plantae
macrosocpic, eukaryotic, multi celled and autotroph
What are the divisions below kingdom?
Phylum, class, order, family, genus, species
What is the kingdom animalia
Macroscopic, eukaryotic, multicelled, heterotroph
What is the kingdom eubacteria
Procaryotic, autotroph and heterotroph, unicelled
What is the kingdom archebacteria
Procaryote, autotrophs, Found in extream enviroments, unicellular
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
