Question

If the population density of a certain marine species is 3 per cubic meter of water, then what is the total population of the species in a body of water that is 1,000 cubic meters in volume?

Answer 1

a. 3000

Step-by-step explanation:

Answer 2

`3000`

Step-by-step explanation:

Given

Population Density of marine species population
`= 3` cubic meter of water

Total volume of water
`= 1000` cubic meters

The number of species in a given habitat

`= p_d * S`

Where
`p_d` is the density of population per unit area or volume

S is the size of habitat for a given population. It can be area , volume or any other unit of measurement.

Substituting the given values in above equation, we get -

`3*1000\\= 3000`
