Unit One Flashcards
Population density
number of organisms of a particular species per unit area
Biotic potential
an organism in an innate potential for an increase in numbers
Exponential growth
number of organisms continue to increase at the same rate year after year
Logistical growth
number of organisms grows exponentially initially until the resources are maximized and the carrying capacity is reached
10% rule
when energy is passed from one trophic level to the next only 10% of energy is passed on
Carrying Capacity
the maximum amount of population size in an environment over a long period of time
Stationary Population
a population that remains same in size over time
Stable Population
age structure remains constant

“nurturing” organisms that nurture their young
R-strategy
“lay’me and leave em” organisms laying eggs and leaving them
