Dry masses are used to work out the pyramid of biomass because the weight and density of wet mass can fluctuate. Water can disappear from the mass, causing it to lose weight. Adding more water will make it heavier and denser.

Many organisms contain a very high proportion of waterwhich can be misleading

Dry mass changes are a more reliable indicator of change/growth

How is stoichiometry used to calculate energy released when a mass liquid freezes?

The mol is involved in many chemical calculations. And the molar mass mass is calculated from the chemical formula.


What is the amount of mass in a given volume?

The mass in a given volume can be calculated from the density of the substance. Density = mass/vol so mass = density x volume


Which value of an element is calculated using both the mass and relative abundance of each of the naturally occurring isotopes of this element?

The atomic weight.


What is the percent by mass of naHco3 in a solution of 40.0g naHco dissolved in 800.0ml of h2o?

First of all, you need to know the density of the water. The density can be calculated by 1g/ml. Then the mass of H2O can be calculated by DXV=1x800. Then the total mass of the solution is the mass of solvent plus mass of solute. The percentage is 4.76 for this solution.


When is the mass of an electron regarded as zero?

The mass of an electron is regarded as zero when it is at rest. The mass of an electron or any particle is calculated by using its momentum and its energy. The mass of an electron is related to its momentum which is zero when the electron is not moving. So when the electron is at rest its momentum is zero and thus its mass is zero. When an electron is moving its mass is no longer zero as its momentum is not zero. It is calculated by using the following equation: Mass = Energy / (Speed of Light)2The mass of an electron increases as its energy increases and it increases even more when it is moving at a higher speed. So when the electron is at rest and its momentum is zero its mass is also zero.

How much biomass can the human get from a 500-kg chicken?

The amount of biomass that a human can get from a 500-kg chicken is approximately 357.5 kg. This is calculated by multiplying the mass of the chicken by the percentage of edible biomass, which is typically around 70%. So, 500 kg * 0.7 = 350 kg.


What is a synonym of biomass?

What are the science behind biomass?

If I ignore your horrible grammar, I think you're asking what biomass is/means... correct? Biomass is the dry mass of a once living organism. So biomass is the mass of an organism minus the weight of the water in/on the organism.


What is the total dry mass of an organism?

The total dry mass of an organism equals biomass. How biomass is measured depends on why it is being measured. It can be measured as the natural mass or as it is. It can also be measured in terms of dry, organic mass. And sometimes just tissues count or just bones.


Is biomass widespread?

"Biomass" is the mass of living (and dead) organisms. So...yes, the Earth is covered with organisms, all of which add biomass.

What is the difference in mass and biomass?

biomass is like wood, cornstalks, basically any thing alive or that has died (recently) mass is how much matter is in something


What is biomass and what can it do?

Biomass is effectively dried up tissue mass. If you take a living thing and dried it out you would have its biomass. From that you can see how much energy store there is.
