What is the difference between density dependent and density independent limiting factors?

• Density dependent factors change according to the population size, while density independent factors do not.

• Density dependent factors are always biotic, while density independent factors are always abiotic.

• Density independent factors increase the population size, while density dependent factors decrease it.

• Density dependent factors are not affected by the environment, while density independent factors are.

What is symbiosis?

• A type of population growth

• A relationship between two different organisms living in close physical association

• A method of classifying organisms

• A process by which an organism changes its environment

Which of the following is a characteristic of logistic growth as opposed to exponential growth?

• The growth rate accelerates throughout

• The population size exceeds the carrying capacity of the environment

• The rate slows down as the population reaches the carrying capacity

• The population size is not affected by the availability of resources

What does point 'c' on the logistic growth graph represent?

• The beginning of exponential growth

• The point of faster population increase

• The carrying capacity of the environment

• The point where resources are no longer limiting

In the context of the graphs provided, what would happen to the population size if more resources were available than shown initially?

• The population would decrease

• The carrying capacity would remain unchanged

• The population would die off

• The carrying capacity would increase, allowing for a larger population size

If there were less resources available than shown here, how would the logistic growth graph be affected?

• The carrying capacity would never be reached

• The carrying capacity would increase

• The population would grow exponentially without limit

• The carrying capacity would decrease, leading to a smaller population size
