Question

in any population, certain factors may enhance population growth while others may limit or even cause a population to decline. we can describe these factors as either density dependent or density independent. drag each factor to the correct classification.
density dependent density independent
food resources fire severe weather parasites climate change territorial aggression

Explanation:

• Density - Dependent Factors: These factors have a greater impact when the population density is high.
• Food resources: As population density increases, competition for food (a limited resource) intensifies.
• Parasites: Higher population densities can facilitate the spread of parasites among individuals more easily.
• Territorial aggression: In denser populations, there is more competition for territory, so territorial aggression becomes a more significant limiting factor.
• Density - Independent Factors: These factors affect the population regardless of its density.
• Fire: A fire (e.g., a wildfire caused by lightning) can destroy a habitat and impact the population without being related to the population's density.
• Severe weather: Events like a hurricane or a severe drought affect the population in a way that is not dependent on how many individuals are present in an area.
• Climate change: Long - term changes in climate (e.g., rising global temperatures) influence populations uniformly across different density levels in a region.

Answer:

• Density Dependent: Food resources, Parasites, Territorial aggression
• Density Independent: Fire, Severe Weather, Climate change
