There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
Explanation:
First of all let's see, what's an <em><u>ecosystem</u></em><em>?</em>
- the ecosystem is defined as the result of what happens when a community of living organisms shares and interacts within their environment.
What this means is that the ecosystem is a product of a <em>specific community</em>. There are several types of ecosystems, for example, a marine ecosystem, the rain forest ecosystem etc.
Now, what's a <em><u>community</u>?</em>
- A community in itself is a group of beings that share something in common and work, interact, and live together.
What happens with the community is that the definition of it does not extend to the specifics of which types of ecosystems can come out of the myriad of communities that exist.
Conclusion: Therefore, a community is a formed group of beings with common locality and with a capacity to come together under a common denominator to establish as specific mode of existence, namely, an ecosystem.
