How does our pollution affect a watershed?
A. It doesn’t. A watershed is a shed full of water so it is contained.
B. Runoff carries pollution into our lakes and streams which contaminates our water source.
C. Chemicals don’t affect water because it gets filtered out through the water cycle
D. It stops the water cycle from happening, which causes a drought
B. Runoff carries pollution into our lakes and streams which contaminates our water source.

Fertilizer is a common pollutant found in most watersheds. How does an increase in fertilizer in a watershed affect our water source?
A. It doesn’t. Fertilizer is great for the environment.
B. It causes an increase in algae blooms which then suffocates life that exists in the water
C. It helps to grow plants which give more oxygen to plant life in the water.
D. It purifies our drinking water naturally.

What three things are needed for life to exist?
Water, stable temperature and presence of oxygen
Water, Carbon Dioxide, shelter
Clothing, food, carbon dioxide
Water, stable temperature and presence of oxygen
How are biodiversity and sustainability of an ecosystem related?
A.If you have low biodiversity then that means you don’t have a lot of competition so your ecosystem is more stable
B.If you have high biodiversity then you have too many species in one place and your ecosystem dies.
C.High biodiversity means an ecosystem will be more sustainable because there is more energy at each level available
D.The two concepts are not related
High biodiversity means an ecosystem will be more sustainable because there is more energy at each level available
