Population Density
What is the equation for population density?
number of organisms/total area
Any factor that causes a population to decrease.
Limiting Factor
The remains of dead organisms that humans use for gasoline.
Fossil Fuel
The total number of organisms per square meter.
population density
The total number of organisms that an area can sustainably carry for an extended time.
Carrying Capacity
What is the equation for area?
This type of limiting factor is living.
Biotic
The chemical symbol C stands for this element.
Organisms living close together in distribution with no randomness.
The type of growth pattern seen in a population of organisms.
Distribution Patterns
What is the population density of 25 organisms living in 5 square meters?
Don't forget your units! (organisms/square meter)
5 organisms/square meter
Give 3 examples of abiotic limiting factors.
This organelle is where plants make C6H12O6 during photosynthesis.
chloroplast
This type of distribution shows organisms living with a regular pattern.
Uniform Distribution
When organisms live in this distribution pattern they have no set pattern.
Random Distribution
What is the population density of 30 organisms living in a plot of land that has a length of 5m and a width of 6m?
Don't forget your units! (organisms/square meter)
1 organism/square meter
A population that has limiting factors will tend to have this type of growth pattern or curve.
Logistic
C6H12O6 and O2 are considered to be the __________________ of photosynthesis in the equation.
products
This type of growth is seen when organisms have plenty of resources to grow and grow.
Exponential Growth
This type of growth is caused by limiting factors and the population will reach carrying capacity.
What is the population density of 80 organisms living in a plot of land that is 4m x 5m?
Don't forget your units! (organisms/square meter)
4 organisms/square meter
A population that has nearly no limiting factors will tend to have this type of growth curve.
Exponential
CO2, H2O and sunlight are considered to be the _______________ in the photosynthesis equation.
Reactants
This greenhouse gas is emited into the atmosphere by plants, animals and the burning of fossil fuels.
Carbon Dioxide (CO2)
The organelle in plants and animals that makes ATP.
Mitochondria
