5 kelps per square meters
Explanation:
<em>The population density would be </em><em>5 kelps per square meters</em><em>.</em>
The population density for an organism is defined as the total number of the organism living per unit particular area at a specific time.
Mathematically, the population density for an organisms is expressed as:
Number of organisms/Land area
In this case:

Area of land = 400 square meters
Hence, population density of kelp = 2000/400
= 5 kelps per square meters
