What is carrying capacity (K) in a population?
What is carrying capacity (K) in a population?
- The maximum capacity of humans to carry resources
- The age at which organisms die due to old age
- The number of organisms an environment can support (correct)
- The theoretical number of offspring an individual can produce
According to the Malthusian Principle, what happens when offspring are produced in excess of carrying capacity (K)?
According to the Malthusian Principle, what happens when offspring are produced in excess of carrying capacity (K)?
- The excess offspring are sent to establish new populations elsewhere
- The excess offspring thrive and lead to rapid population growth
- The excess offspring are cared for by the stronger individuals in the population
- The excess offspring must die to bring the population back into equilibrium (correct)
How does variation within populations impact the survival and reproduction of individuals?
How does variation within populations impact the survival and reproduction of individuals?
- Variation leads to rapid extinction of populations
- Variation affects the ability of individuals to survive and reproduce (correct)
- Variation directly increases carrying capacity (K)
- Variation has no impact on survival and reproduction
