What is the definition of Population?
A group of individuals of the same species living in a specific area.
What is Population Density?
The number of individuals per unit area or volume.
What is Population Distribution?
The way in which individuals are spaced within a given area.
What are the three types of population distribution?
- Clumped
- Uniform
- Random
What is the difference between clumped, uniform, and random distribution?
- Clumped: individuals are grouped together
- Uniform: individuals are evenly spaced
- Random: individuals are distributed without a predictable pattern
Why might populations be in either of the three distribution patterns?
Factors like resource availability, social behavior, and environmental conditions influence distribution patterns.
Fill in the blank: Population density can be calculated by dividing the total number of individuals by the _______.
