Population Density
The total number of organisms per square meter. Total number of organisms divided by the area.
Population density
Any factor that causes a population to decrease. These can be biotic or abiotic.
Limiting factor
The type of growth pattern seen in a population of organisms.
The process where plants take water, carbon dioxide and sunlight to make sugar and oxygen.
Photosynthesis
The symbol for carbon
C
What is the formula for the area of a square plot of land with length and width?
length x width
The type of growth seen when a population has unlimited, or an excess of resources. Line A

Exponential growth
Organisms living all over the area, no pattern seen.
Random distribution
What are the reactants of photosynthesis?
Carbon dioxide, water and sunlight
Chemical formula for carbon dioxide is what?
CO2
What is the equation for population density?
number of organisms / total area
The type of growth seen in populations when there are limited, or not enough resources. (Line B)

Logistic growth
Organisms living together, not random.
Clumped distribution
What are the products of photosynthesis?
Sugar and oxygen
What puts carbon into the ground?
Death of organisms
What is the area of a 2m x 3m plot of land?
Make sure to have the correct units with your answer.
6m2
What could cause a population to overshoot and grow beyond their carrying capacity?
Abundance of resources: food, water, sunlight, space/shelter, no predators, no disease, no competition, no natural disasters
Organisms living very regularly with a pattern.
Uniform distribution
Where do plants get the carbon to make sugar during photosynthesis?
The atmosphere
What is the population density if there are 25 organisms living in a 5m x 5m area?
Make sure to show your work and have the units in your answer.
1 organisms/m2
What could prevent a population of organisms from reaching carrying capacity?
Limited resources like: no food, no water, no sunlight, no mates, lack of space, natural disasters, diseases, competition, predators, etc...

Where in the plant cell does photosynthesis take place?
Chloroplast
How is carbon removed from the atmosphere?
photosynthesis
