3. A population of 820 insects lives in a 1.2-acre area. They gather nectar from a
katen-ka-za [31]

Answer:

The plants have the higher population density. This is because, when compared with that of the insects, the number of plant species per acre area is higher; 2800 compared to 683.3

Explanation:

The number of individual species per unit area of land is known as the population density. Population density describes how crowded or spaced out a given species is in a particular area. The higher the population density, the more crowded the species are and vice versa. The formula for calculating population density is given as:

Population density = Number of species/land area

Population density of the insects = 820/1.2 = 683.3 insects/acre

Population density of the plants = 560/0.2 = 2800 plants/acre

Therefore, the plants have the higher population density.

This is because, when compared with that of the insects, the number of plant species per acre area is higher.
