Question

population growth
whats the difference between exponential growth and logistic growth?
what is carrying capacity?
what are the 4 types of limiting factors? give examples of each.

Explanation:

Exponential growth is unrestricted, increasing at a constant rate. Logistic growth slows as it approaches carrying capacity, the maximum population an environment can sustain. Limiting factors are biotic (e.g., predation) and abiotic (e.g., temperature), density - dependent (e.g., disease) and density - independent (e.g., natural disasters).

Answer:

1. Exponential growth is unrestricted, increasing at a constant rate; logistic growth slows as it nears carrying capacity.
2. Carrying capacity is the maximum population an environment can sustain.
3. Biotic: predation (e.g., lions preying on zebras); Abiotic: temperature (e.g., extreme cold affecting plants); Density - dependent: disease (e.g., flu spreading in a human population); Density - independent: natural disasters (e.g., earthquakes affecting populations).
