what a density-independent limiting factor is?
15717
Density-independent factor, also called limiting factor, in ecology, any force that affects the size of a population of living things regardless of the density of the population (the number of individuals per unit area). ...

Density measures the amount of mass per unit of volume in a substance. Concentration describes the amount of a substance dissolved in another substance.

K-strategist populations are more commonly regulated by density-dependent limiting factors. ... On the other hand, r-strategist populations are regulated by density-independent limiting factors. They reproduce rapidly until a density-independent factor causes many of them to die.

Answer: Density is defined as mass per unit volume. Specific gravity is the density of a material at a certain temperature divided by the density of water at a certain temperature; the reference temperature is usually 20 degrees Celsius. Pycnometers measure volume.

A population with a high birthrate, a large, dense population, and a population with a high immigration rate. An example of a density-independent limiting factor would be: The eruption of a volcano.

Density and pressure/temperature Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

Density. The density of an atom is determined by the number of atoms a substance per unit volume of the material. Solids will have a higher atomic density than gases.

Density is defined as the mass of a certain volume of a substance. ** here, we manipulate the VOLUME of the water. If volume is the independent variable (x axis) and mass is the dependent variable (y axis) then the slope of the graph will be the density of the substance.

Density independent abiotic factors depend on the number of individuals in a population, whereas density dependent do not. ... Density dependent abiotic factors affect populations relative to their population size and can involve resource shortages that push a population beyond its carrying capacity.

Density. Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume.

No matter what size sample of water you measure, the relationship between the mass and volume will always be the same. Because D=m/v, the density is the same for any amount of water.

Density-independent factors, such as environmental stressors and catastrophe, are not influenced by population density change. ... These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons.

Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment.

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

As a common rule of thumb, for most pure liquids temperature is inversely proportional to the density. That is, temperature rise lowers the density, and lowering temperature will increase density.

The following things are affected by a density-dependent limiting factor: A population with a high birthrate, a large, dense population, and a population with a high immigration rate. An example of a density-independent limiting factor would be: The eruption of a volcano.
