what is the difference between a density dependent and density independent factor?

Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation. Density-independent regulation can be affected by factors that affect birth and death rates such as abiotic factors and environmental factors, i.e. severe weather and conditions such as fire.

The independent variable is the amount of dish soap, while the dependent variable is the amount of foam produced.

what is the difference between density and vapour density? Density is the ratio of mass of a substance to its volume. Vapour density is the ratio of weight of a certain volume of gas or vapour compared to the weight of an equal volume of hydrogen .

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.

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.

Density is a measure of mass per unit of volume. Density is a measure of mass per volume. ... An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

n in this unit. Density may be calculated from a separate mass and volume measurement, or, in the case of liquids, may be determined directly by the use of an instrument called hydrometer. hich it is not soluble, and the volume of liquid displaced measured.

Density, however, is the mass of an object divided by its volume. ... This means that the lead has a higher density than cotton. To summarize, volume and density measure two different things. Volume measures how big the space of something is, whereas density measures the how much mass there is in this space (volume).

What is the difference between density and mass? Check all that apply. ... The mass of a substance is independent of the amount of the substance, while density depends on the amount of the substance. The density of a substance is independent of the amount of the substance, while mass depends on the amount of the substance.

Understanding this difference is important as the entire inventory policy for an item is based on this. Independent demand is demand for a finished product, such as a computer, a bicycle, or a pizza. Dependent demand, on the other hand, is demand for component parts or subassemblies.

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.

Pressure does not depend upon the amount of substance because it is defined as force per unit area. The definition itself eliminates the need of looking for how much of quantity is causing that much pressure. Pressure is an intensive property (independent of amount).

Density is simply a ratio between the mass of a sample and it's volume. Specific Heat is a measure of how much thermal energy is required to raise the temperature one degree Celsius of one gram of the material. There is no correlation between the two quantities.

Density-independent factors affect per capita growth rate independent of population density. Examples include natural disasters like forest fires. Limiting factors of different kinds can interact in complex ways to produce various patterns of population growth.

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.

Buoyancy is independent of the gravity it is in because buoyancy is determined by the relative densities of the material being buoyed and the the fluid that is being displaced. The common name for the density related to buoyancy is specific gravity. ... Object can float in fluids other than water.

Contrast is the amount of separation between dark and light tones, whereas density refers to the opacity of exposed silver in the negative. A dense negative is effectively a thicker negative which requires more exposure to enlarge, usually resulting in increased apparent grain.
