Chapter 13, Problem 38A

Summary Introduction

To determine:

A population, community and ecosystem in an area and biotic and abiotic factors affecting them.

Introduction:

In an ecological hierarchy, an organism is the smallest unit. An organism belongs to a single species and the members of a species make up the population. Many different population of a particular region, which interact with one another makes up a community. The community includes all the living organism and community along with all the abiotic factors of that region makes up an ecosystem.

Explanation of Solution

Apond ecosystem can be found in any region. In a pond ecosystem, the total number of individuals of a single species represents the population of that species. For example, the total number of a single type of fish in the pond is a population or the total number of plants of water lily represents the population of water lily. The community is all the living organisms in the pond. Fishes, phytoplankton, algae, and other organisms. The biotic factors are comprised of all the living components. The abiotic components are the temperature of water, oxygen concentration in water.
