The document discusses biodiversity and evolution, focusing on the stability of communities in different habitats like corn fields and forests. It defines limiting factors, which affect population sizes, and explains carrying capacity as the maximum number of individuals an environment can support sustainably. Additionally, it outlines how to calculate population density and poses a question about the effects of increasing population density.

Which community is most stable?

4. Limiting Factor
A limiting factor is anything that constrains a
population's size and slows or stops it from
growing. Some examples of limiting factors
are biotic, like food, mates, and competition
with other organisms for resources.

5. Carrying Capacity
Usually defined as the average
maximum number of individuals of a
given species that can occupy a
particular habitat without permanently
impairing the productive capacity of
that habitat.

6. Activity
Population Density

10. How do you determine the area
distribution of a given population?
Population density is the total number of
individuals of a population within a given
area or region. It is calculated by dividing
the total population of a geographic area
by the size of the area: (DP = total
population / land area).

11. Infer what will happen If population
density increases?
