Which factor is a density-dependent limiting factor on the population of a species?

• seasonal variation
• natural disasters
• unusual weather
• predation

What is happening at the 'A' on the graph?

• the population overshoots above the carrying capacity

• the population stops growing

• growth begins to slow down due to limited resources

• growth is speeding up due to an abundance of resources

• birth and death rates
• carrying capacity
• height of the space
