3. A population of 820 insects lives in a 1.2-acre area. They gather nectar from a
population of 560 flowering plants. The plants live in a 0.2-acre area. Which population
has greater density, the insects or the plants? Why?
Answer:

Respuesta :

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.

The population which has greater population density is the flowering plants with a population density of 2800 per acre.

Definition:

The population density is a measure of how crowded an area is. In essence, the population density of an area is simply defined as the number of species per unit land area.

Mathematically, the population density is evaluated as follows;

  • Population density = No. of species/Land area.

As a result;

  • The population density of the insects is;

P.D(insect) = 820/1.2 = 683.33 insects per acre.

  • The population density of the flowering plants is;

P.D(flowering plants) = 560/0.2 = 2800 flowering plants per acre.

Consequently, the population which has greater population density is the flowering plants with a population density of 2800 per acre as opposed to 683.33 per acre of the insect population.
