10467555171 | Uniform distribution | results from intense competition of antagonism between individuals | 0 | |
10467557088 | Random distribution | occurs when there is no competition, antagonism, or tendency to aggregate. | 1 | |
10467618337 | Clumping | is the most common distribution because environment conditions are seldom uniform. | 2 | |

10467680984 | Logistic population growth | occurs when the growth rate decreases as the population reaches carrying capacity (represented by an S shaped curve on a graph) | 4 | |
10467685320 | Carrying capacity | is the maximum number of individuals in a population that the environment can support. | 5 | |
10467690763 | Exponential population growth | when the resources availability is unlimited in the habitat, the population grows at a constant rate. (represented by a J shaped curve on a graph) | 6 | |
10467909549 | Disruptive selection | extreme traits are favored over intermediate traits | 7 | |
