Populations Flashcards
1
Q
carrying capacity
A
maximum population size that an environment can support
2
Q
abiotic factors that can affect population size
A
- natural disasters
- water availability
- rainfall
- temperature
3
Q
biotic factors that affect population size
A
- competition/war
- predators
- disease
- birth rate
4
Q
limiting factors that can keep the population at a stable level
A
- disease
- food supply
- conflict
5
Q
k-strategist
A
- limiting factors exert their affect as population grows closer to the carrying capacity
- population gradually levels out
- low reproductive rate, slow development, long lifespan, large body mass
- eg. humans, elephants, lions, sharks
6
Q
r-strategist
A
- population size increases too rapidly that it exceeds carrying capacity
- not enough resources to survive/reproduce
