Density: Factors, the math and more.
The number of individuals per unit area
What is Density?
Organisms will be where they choose no matter what else happens in an are
what is random dispersion?
This makes primary succession take significantly longer?
the lack of soil
This makes secondary succession significantly faster than primary succession
what is the presence of soil
This term describes the range of life in an ecosystem
what is biodiversity
A density dependent factor that deals with low food, water and space availability.
What is Limited Resources?
This dispersal pattern is when organism group together throughout their area
what is clumped dispersion?
This is a typical pioneer species of primary succession
what are lichens
this is a typical pioneer species for secondary succession
what are weeds and grasses
This describes the biotic and abiotic factors in an area
what is an ecosystem
This density independent factor includes things like paving roads, deforestation, farming and construction.
What is Human Activity?
This dispersal pattern that happens when organisms deal with territoriality. Animals are typically evenly spaced out.
what is uniform dispersion?
This is a good example of primary succession because of the barren rock that is produced when it cools.
This is a good example of secondary succession because there was something previously there.
forest fire (any correct example)
This term describes animal who eat producers.
what are primary consumers
2.15 moose per square mile
This type of growth is limitless.
This is the end result of primary succession
what is a climax community
this is the end result of secondary succession
what is a climax community
Why are conservation efforts important in places like national parks?
To help increase biodiversity
The idea that an ecosystem can only support so many organisms of a population in an area on regular basis before environmental resistance occurs.
What is Carrying Capacity?
This type of growth is limited by environmental resistance factors.
What is exponential growth?
Which is not primary succession
A.Volcanic eruption
B.farming
C.Eroded rock/sand
B. Farming
Which is not secondary succession:
A. Deforestation
B. Glaciers moving
C. forest fire
B. Glaciers moving
describe how high biodiversity increases resiliency of an ecosystem?
The more life you have in an area, the more likely you have organisms that can take on roles of other populations that were lost.
