Lab: Environmental Changes in a Watershed

300+ words

In the lab activity, I used a virtual watershed to demonstrate how pollutants enter and flow through the watershed. I constructed food chains to show how biotic factors are related. I also predicted and modeled how human activity affected the biotic factors in an ecosystem. Based on my observations, I can conclude that biotic and abiotic factors are closely linked and that human activity that changes the environment, like pollution, can affect all the other parts of an ecosystem in a negative way.

Explanation:

To examine how environmental changes affect the health of a watershed and to predict the effect of human activity on the watershed

Time Approximately 60 minutes

Question How do environmental changes affect both living and nonliving things in a watershed?

Summary In this lab, you will study a virtual model of a watershed to see how point and nonpoint source pollution affect the watershed. Next, you will create food chains. Finally, you will model scenarios of environmental changes and observe the effect of these environmental changes on a food chain you created. This will help you understand how the overall health of a watershed is affected by changes in environmental factors, such as populations of organisms, water quality and flow, and human activity

Hope this helps

the answer to fill in the blank in this question would be the word resource, it is defined as the money, material or people (since human resource is a very valuable good) that a company or a person has at disposition (meaning they can use the resource as they see fit), to be able to complete a task or achieve a goal.  

this is a good question! i'll do some research and come back when i have the answer!
