Question | Answer |
Exponential Growth | J-shaped curve; growth rate is a characteristic of many species that grows rapidly. |
Carrying Capacity | Maximum population size that the environment can support w/o depleting resources. |
R-Selected | Rapid population growth |
K-Selected | Species that reproduces slowly, where a resource is constant but available in limited quantities. |
Founder Effect | Genetic drift due to a few individuals starting a new population of the same species. |
Bottleneck Effect | Genetic drift due to a massive population loss. |
Can organisms exceed their carrying capacity? | Yes, but they may experience shortages of food or their resources leading to a population crash. |
J and S curve | 1.Logistic growth curve; changing number over time because of the populations density. 2. Exponential growth curve; leads to population crash. |
r=B+I-D-E | rate= Births+Immigration-Deaths-Emigration |
Interspecific | Interactions between different species. |
How can predation be positive for population size? | Rise in resources because of reduction in population. |
Options to control invasive species | 1. Hunt them to reduce population 2.Limit food sources |
How can predation be negative for population size? | Predation can limit the population growth |
Intraspecific | Interactions between the same species. |
