Although both macro algae and mangrove trees are multicellular and share many of the same structural features, macro algae are not true plants. Also, mangrove trees and marsh plants typically live in brackish water rather than salt water and are not completely submerged, as opposed to macro algae.

Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.

To find: The total population size of the frogs in the pond.

Method: Using unitary method of proportions

Solution:

Let p be the density of the frogs present per square meter.

Let A denote the total area of the pond.

∴ p = 12 frogs/m² and A = 370 m²

The total number of frogs in the pond is given by,

$p \times A = 12 \times 370 = 4440$

Therefore, there are 4440 frogs in the pond.
