Chapter 3: Problem 2

Define and compare the terms species, population, and ecosystem.

Short Answer

Expert verified

Species refers to a group of similar organisms capable of interbreeding, population denotes a group of the same species inhabiting a specific area, and ecosystem refers to a community of organisms and their physical environment interacting as a system. The complexity and components increase from species to populations to ecosystems.

Step by step solution

Define species

The term 'species' refers to a group of similar organisms that can interbreed to produce fertile offspring. It is the basic unit of biological classification and a basic unit of biodiversity.

Define population

A 'population' is defined as a group of individuals of the same species inhabiting a specific geographic area at a specific time. They share the same gene pool.

Define ecosystem

An 'ecosystem' refers to a community of living organisms (plants, animals, microbes) in conjunction with the nonliving components of their environment (like air, water, and mineral soil), interacting as a system. This includes all the different species within an area and the dynamics of their interactions.

Comparison

Species are the smallest of these three units. Several members of the same species living together form a population. Multiple populations interacting with each other and the surrounding environment form an ecosystem. Ecosystems are the largest of the three biological organiztion. Each concept is progressively more complex and includes more components than the last.
