Biomass is the overall mass of the animals.
There are billions of plankton, but they have negligible mass. Compared to the shark which is massive, but in small numbers.

The answers the one at the bottom so if the shark has the biggest biomass then why would it be plCaced at the top

Like i said, there are very few sharks even though they have the biggest mass. So they're the least overall mass, biomass.

[QUOTE=AlexsNan;47918147]Like i said, there are very few sharks even though they have the biggest mass. So they're the least overall mass, biomass.[/ sorry for bein a pain but does that mean the lower no of any organism the lower the biomass?

Soo high biomass isn't about the overall mass of an organism it's about having lots of organisms with a set mass??

Think about there being a massive number of plankton, so although they have a tiny mass of each one, their combined biomass is still rather large. Compared to the shark which has a large mass per shark but very few in numbers.

Lots and lots and lots of plankton, small mass, large biomass
small number of sharks, massive mass, small biomass

think of biomass as overall mass

and animal plankton are roughly similar in number to plank plankton, just a larger mass, thus larger biomass
