Population Growth Flashcards
When populations are in their own ways
Random
When populations are in even rows
Uniform
Two density independent factors that can affect a population
Weather, climate
Three density dependent things that affect a population
Food, disease, and stress from over population
3 negative impacts that overpopulation can have in a population
Overcrowding, mates, starvation
S graphs are
Logistic
J graphs are
Exponential
How many population members can be found in a given area is _________ _________
Population density
Slow going populations because their population size is usually near to the carrying capacity
K- Strategists
Many species grow exponentially when environmental conditions support this
R- Strategists
Limiting conditions such as weather and climate are called
Density independent factors
The growth rate
The number of deaths minus the number of individuals that were born
The _________ growth model is used to model population growth that is limited by density-dependent factors
Logistic
If the population stays the same throughout many years and steadily grows it’s called
Exponential growth
The population size that an environment can sustain is called
Carrying capacity
