transfer of biomass

How is biomass measured as?

Dry mass of organisms/ tissue

Mass of carbon that organisms/ tissue

Chemical E of organisms burned in 02

What is net primary production

The rate at which energy is transferred into the organic molecules that make up new plant biomass

Chemical energy store in plant biomass after respiratory losses to the environment have been taken into account

What is dry mass

Mass of organism or tissue after water removed

Used to calculate biomass of population/area

What is gross primary production

The rate at which energy is incorporated into organic molecule in the plants in photosynthesis

Chemical energy store in last biomass in a given area o volume in a given time

What units can be given to biomass and why

Unit of time

As biomass changes over time (e.g trees dying)

If average biomass of a group of oak trees over a year and is 13,000kg then what is biomass?

13000kgy^-1

If the average of biomass of 1m² of grass over a year is 0.15kgm^-2 then what is biomass

O.15kgm^-2yr^-1
