Carrying Capacity: The amount of food that an area of land will yield. Therefore, the number of people that an
area of land will support.

• Humans are really good at increasing our carrying capacity.

Limiting Factors: A factor that causes a population to decrease in size.
Density Dependent Factors
(Other living things)
Density Independent Factors(Non-living / Abiotic)
• Limiting Factors: A factor that causes a population to decrease in size.– Sunlight– Water– Temperature

This is a picture of food aid being delivered to an area of the world that needs it very badly.
Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another.
• Concealing Coloration: When an animal hides itself against a background of the same color / pattern.

• Disruptive Coloration: When stripes, spots or other patterns make it hard for other animals to see the outline of their bodies
• Disguise: This is like concealing coloration except that the animals blend in with their surroundings by their shape and/or texture rather than color.
