Question

What best defines a population?

The variety of traits a species has
A group of organisms of one species
All the different plants, animals, fungi, and microorganisms
All the different habitats and ecosystems found around the planet

Answer 1

The correct answer is B. A group of organisms of one species

Step-by-step explanation:

The first option is suggesting that population is the variety and different traits of a species. However, the meaning of population has nothing to do with the traits of the animals, just the number/amount of them.

(this is incorrect)

The second option is suggesting that population is a group of organisms of one species, which fits into the correct definition of "population".

(this is correct)

The third option is suggesting that population is all of the different plants, animals, fungi, and the microorganisms. However, once again we are talking about the amount of the species, not the variety of things like traits or different species. Similar, but still very different.

(this is incorrect)

The fourth option is suggesting that population is all the different habitats and ecosystems around the planet. But that is not what population is. This is talking about the varieties of the worlds ecosystem and different living spaces and styles.

(this is incorrect)

From the descriptions above you can understand that population is the number of organisms in a group or species, not the variety.

Answer 2

The correct answer is - A group of organisms of one species.

A population is a term that is used to describe the number of the individuals of one species. The population of a species can vary, and it can be very large, medium sized, or very low and on the verge of existence.

Also, this term refers to the number of organisms of the same species in a particular habitat. As that may lead to a little bit of confusion to explain... We may have few packs of wolves living in the eastern part of the United States, and we may have few packs of wolves that live in the western part of the United States. Despite all wolves being from the same species, the population do not have any contact between them and they are very far way from one another. Also, they live in different habitats, so we may say that the population of the wolves in the western part is ''blank'' and in the eastern part is ''blank'', but not to use both populations to describe all the individuals of the species in the country.
