Question

multiple choice 20 points a student studies the importance of populations in ecosystems. the student visits a garden and counts the different types of plant and animal species and records three observations in a chart. - there are many types of plant and animal species. - each species consists of a large numbers of organisms. - each species interacts with other species in the ecosystem. based on the observations, the student defines a population as a group of individuals of different species that live together and depend on each other for their survival. does the student accurately define a population? - yes. different populations make an ecosystem. - no. individuals in a population do not depend on each other for survival. - no. a population must consist of a group of individuals belonging to the same species. - yes. a population must consist of a group of individuals belonging to different species.

Explanation:

To determine the correct answer, we recall the definition of a population in ecology: a population is a group of individuals of the same species living in a particular area. The student's definition includes "different species", which is incorrect. Let's analyze the options:

• Option 1: Incorrect, as the student's definition is wrong (mixes species).
• Option 2: Incorrect, the issue is about species, not dependence for survival.
• Option 3: Correct, because a population must be of the same species, not different.
• Option 4: Incorrect, contradicts the ecological definition of a population.

Answer:

C. No. A population must consist of a group of individuals belonging to the same species.
