- Q2
repeated production of offspring at intervals throughout the life cycle of an organism
iteroparity30s - Q3
growth, particularly of a population, in which the increase occurs in the same manner as compound interest
exponential growth30s - Q4population increase that results in an S-shaped curve; growth is slow at first, steepens, and then levels off due to environmental resistancelogistic growth30s
- Q5
largest number of organisms of a particular species that can be maintained indefinitely by a given amount
carrying capacity (K)30s - Q6
abiotic factor, such as fire or flood, that affects population size independent of the population's density
density-independent factor30s - Q7
biotic factor, such as disease or competition, that affects population size in a direct relationship to the population's density
density-dependent factor30s - Q8
results when members of a species attempt to use a resource that is in limited supply
competition30s - Q9
interaction in which one organism (the predator) uses another (the prey) as a food source
predation30s - Q10
Populations can sometimes show extreme fluctuations in size and growth rates in spite of extrinsic and intrinsic regulating mechanisms—such wild fluctuations with no recurring pattern are termed chaos.
