Population Ecology

Question 1

Population Ecology

Answer 1

The dynamics of a population overtime, which oversees deaths and birth rates

Question 2

2 models of Population Ecology

Answer 2

1. Exponential Growth: The accelerated growth pattern of a species as a result in an environment with unlimited resources, unrealistic since environments will always have limiting resources
2. Logistics Growth: The result of growth due to limited resources, more realistic since resources are limiting overtime

Question 3

What’s Carrying Capacity (K)

Answer 3

The max amount of organisms an environment can support, where K isn’t constant due to seasons, events, and competition

Question 4

Population Growth Regulation

Answer 4

Factors that increase or decrease the size of an environments population

Question 5

Two types of Population Growth Regulation

Answer 5

1. Density-Dependent: Refers to regulating the growth of a population through biological factors such as Disease, Competition, and Predation
2. Density-Independent: Refers to regulating the growth of a population through physical factors such as Fires, Droughts, and other catastrophe
