Which are density-dependent factors that limit population size?I. DiseaseII. SpaceIII. EarthquakeElimination ToolSelect one answerAI only.BII only.CIII only.DI and II only.EII and III only.
Solution
The density-dependent factors that limit population size are factors whose effects on the size or growth of the population vary with the population density. These are usually biological factors and include things like predation, inter- and intra-specific competition, accumulation of waste, and diseases.
In the given options, Disease (I) and Space (II) are density-dependent factors. Disease can spread more easily in a densely populated area, and space becomes limited as population size increases.
On the other hand, an Earthquake (III) is a density-independent factor. Its impact does not depend on the population density but can affect the population size regardless of its density.
So, the correct answer is DI and II only.

Populations are capable of different speeds of growth depending on whether or not they have a carrying capacity. A carrying capacity refers to a limit on the growth of the population. These limits may involve the amount of food, water, space, or shelter in a location. When a population has a carrying capacity, the growth is represented by a logarithmic model, shown below.Population Ecology Growth Graph by Mathboy321 (CC BY-SA 4.0)Which of the following carrying capacity factors is considered density-independent?Elimination ToolSelect one answerAFood.BNatural disasters.CWater.DShelter.
