Answer :
Answer: 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: it the sample response
A drainage basin is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water.
In an ecosystem, there are two types of a factor in there which makes them functional, these factors are as follows:-
- Abiotic factor
- Biotic factor
The watershed affects the biotic factors in several ways:-
- Restricted movement
- Confined space.
- Less population
The watershed affects the abiotic factors in several ways:-
- Less variation
- Less chance of evolution.
- More aquatic species.
These are the changes that occur in the watershed.
