1. SCIENCE 9 BONNIE RICK C. PATIÑO Biodiversity and Evolution

2. Corn Field Forest

3. Corn Field Forest 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

7. 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).

8. Infer what will happen If population density increases?
