Question

1 multiple choice 2 points which example shows a density - dependent factor limiting population size? forest fire destroying nesting areas volcanic eruption altering the landscape spread of disease in crowded conditions temperature drop in winter

Explanation:

• Density - dependent factors are related to population density.
• A forest fire destroying nesting areas is a density - independent factor (it affects the population regardless of its density).
• A volcanic eruption altering the landscape is a density - independent factor (its impact is not related to population density).
• The spread of disease in crowded conditions is density - dependent. As population density (crowded conditions) increases, the spread of disease (which limits population size) becomes more likely.
• A temperature drop in winter is a density - independent factor (it affects the population regardless of its density).

Answer:

Spread of disease in crowded conditions.
