Question

becoming lake stewards
during camp, students collected information about the different life - forms they found at various spots around the lake. some were north, near the residential areas of sucker brook in the city of canandaigua, others were south, near naples creek.
they took a pontoon boat out on the water where they collected samples from different spots on the lake and tested them for pollution. during the week, they searched for salamanders and learned how to count fish populations. they also listened to speakers talk about everything from underwater heroes to the importance of keeping a nature journal. in addition, they learned what they can do to help the environment, like planting trees to prevent soil from eroding into the water. reporting on invasive species when they see one is also important, \and try not to pollute,\ said avery pude, a tenth - grader in the honeoye falls - lima school district.
lori zonowick teaches biology, an area of science that studies living things, at canandaigua academy. she said the kids learned more about where lake pollutants come from and the role they play in the lakes health. they also learned about how invasive species and human behaviors disturb the food chain. (a food chain is the order in which living things depend on each other for food.)
the idea behind the program is that the kids also come to realize how their personal behaviors and those of people they know may be hurting the lake, zonowick said. they also learn how to make changes to stop or even help reverse some of the damage that has been done to the lake.
thanks to the program, zonowick said students \become more stewards of their lake and help to promote its health and spread awareness of whats hurting and whats good for our lake.\
writing prompt: people use pesticides, which are substances used to kill, keep away, or control certain forms of plant or animal life that are considered pests, and these pesticides can wind up in the lake, polluting its water. how will pesticides affect the river and impact the whole ecosystem environment? use details from the text to support your answer (claim).
you can use these sentence starters to help you write your paragraph:

• the pesticide will have a __________ effect on our ecosystem.
• this article explains the use of pesticide...
• pesticides can move through the food chain by...
• runoff carrying pesticides into rivers and lakes causes...
• over time, pesticide buildup in the watershed may lead to...

Explanation:

Pesticides are harmful substances. They can pollute lake water. Through runoff, they enter rivers and lakes, moving through the food - chain. This can disrupt the balance of the ecosystem as different living things in the food - chain depend on each other. Buildup over time can lead to more severe impacts on the health of the ecosystem and the lake environment.

Answer:

The pesticide will have a negative effect on our ecosystem. This article explains the use of pesticide as substances to control pests, and how they can wind up in the lake, polluting its water. Pesticides can move through the food chain by runoff carrying them into rivers and lakes. Runoff carrying pesticides into rivers and lakes causes contamination of the water bodies. Over time, pesticide buildup in the watershed may lead to disruption of the food - chain balance and overall degradation of the lake's ecosystem health.
