<u>The carrying capacity of a population</u> does not affect the spatial distribution of a population
Explanation:
The carrying capacity only affects the number of individuals of a population that the habitat or environment can sustainably support, because it allows for the resources to replenish themselves.
Spatial distribution is how the individuals of the population are distributed across the habitat. They could be clustered, uniform or un-uniform. Distribution could be affected by;
- the distribution of food and other resources
- abiotic conditions like rainfall and sunlight
- the existence of predators or parasites
