Terms in this set (26)
the total number of organisms that an ecosystem can support
A relationship between two species in which both species benefit
A relationship between two organisms in which one organism benefits and the other is unaffected
An interaction in which one organism kills another for food
"mark and recapture" method that allows biologists to estimate the number of animals in a given area
What are some ways to estimate population growth?
A complete enumeration of a population.
The number of individuals added to a population over time
No, they can be biased and slightly overestimates of the size of the population
Are estimates of population accurate?
The difference between the true value and the estimate divided by the true value and the result is multiplied by 100 to make a percentage
The amount of error that occurs for to sampling
Why is the percent error important?
It will be smaller compared to the estimate population size because the Lincoln-Peterson index overestimates the size of the population
How do you think the actual population size will compare to the estimated population size?
The study of interactions between organisms and their environment
competition and predation
Examples of biotic components
Weather and temperature
Examples of abiotic components
A group of organisms of the same species that occupy the same geographical area
Estimation of the total population size
Total number of animals captured and marked on the first visit to an area
Total number of animals captured in the second visit to the same area
Number of animals captured on the first visit that were recaptured in the second visit
