What are some examples of biotic factors
What is other living organisms- predation, competition, symbiotic relationships can all occur
100
This is an example of a diverse community using four different species. In this community, there are 40 total organisms. Distribute the numbers appropriately to get the most diverse community
What is 10 of species 1, 10 of species 2, 10 of species 3, 10 of species 4. -remember, species richness and evenness is important- check car diversity lab
100
This is a population
What is a group of individuals that belong to the same species and are within a certain area
100
These are species that are first on the scene for primary succession
What is pioneer species
100
Eucalyptus, a tree native to Australia would be considered to be this in a food web
What is primary producer
200
These are some examples of abiotic factors
What is air temperature, wind speed, water temperature, pH, salinity, sunlight amount
200
The competitive exclusion principle means this
What is two organisms that occupy the same niche at the same time in the same place will eventually have one organism that goes locally extinct where the two coexist. One will eventually outcompete the other.
200
This is a graph of exponential vs. logistic growth curves
What is - should have line going up like a J for exponential, should have s-shaped curve for logistic.
200
These are the two types of succession. These are the characteristics of each.
What is primary and secondary. Primary is where nothing living exists after a disturbance (lava flow, glacier moraine). Secondary is where a disturbance still leaves soil intact. As succession occurs, it will go from grasses to shrubs, to saplings, to mature forests.
200
Draw a food web with five different organisms in it.
What is arrows should be pointing from an organism to the organism that is eating it NOT vice versa.
300
This is dispersal
What is the movement away from a point of origin or concentration by an individual- this can be limited by climate and abiotic factors
300
Two species or warblers occupy different parts of a spruce tree. One uses the upper branches of the tree, while the other uses the bottom portion of the tree. This is known as what?
What is resource partitioning
300
These are examples of density-dependent factors
predation, competition, disease/plague
300
This is the amount of energy lost between two trophic levels. What is it lost as?
What is 90%. Heat lost to the atmosphere or in feces.
400
The number of white-tailed deer in a 10 Km2 park would be known as
What is density
400
Provide an example and signs for parasitism, mutualism, and commensalism
What is +/0, +/+, +/0 Parasitism: mistletoe and spruce tree Mutualism: sea anemone and clownfish Commensalism: Barnacles and whale
400
This would be a situation where a population would display logistic growth
What is limiting factors- competition
400
The intermediate disturbance hypothesis states this
What is medium levels of disturbance will have higher levels of species diversity because it isn't too high of disturbance to be beyond the tolerance of species, but can also help to open up habitat for less-competitive species.
400
A caterpillar eats a plant that has 1000 J of energy. 550 J are lost in the caterpillar's feces, while 350 is lost as heat from cellular respiration. This is the amount of energy stored in biomass of the caterpillar.
What is 100 J
500
These are the three dispersion modes seen amongst populations and the scenarios in which each usually occur.
What is clumped, uniform, random. Clumped occurs when there is a resource, uniform occurs among highly territorial organisms, random- resources are all over the place- a good example would be dandelion seeds that are carried by wherever the wind blows
500
In this theory, the closer and larger an island is to the mainland, the more species diversity it will have.
What is island biogeography
500
A population of emperor penguins has an annual per capita birth rate of 0.03 and an annual per capita death rate of 0.02. Calculate an estimate of the number of individuals added to (or lost from) a population of 1,000 individuals in one year.
What is 10 individuals will be added 0.03 (bN)- 0.02 (mN)= 0.01 *1000= 10 individuals
500
How is the carbon cycle related to ocean acidification?
What is carbon dioxide breaks
500
This is the role of detritivores in a food web
What is recycle nutrients to be used by primary producers
