Step by step
Solved in 2 steps
- Explain how the presence of algae can indicate either pollution or productivity of a body of water.What is it called when organisms buried in the sediment use special structures to filter plankton from the clear water above? Give an example of an organisms like this mentioned in the text.Why is algae a better source of nutrients than fish?
- Is cleaning plastic from the gyre is worth the risk to marine life? How do you collect small floating trash without collecting small floating organisms?In Eutrophication, excess nutrients can cause algal blooms. However, what happens when the algae eventually die? Bacterial – Increase or decrease Oxygen – Increase or decreaseClimate change and global warming patterns have caused ocean temperatures to increase over the last 50 years. How would the researchers algae farm help fight climate change? What would be the advantage of the algae farm beyond the production of biofuel?
- What happened to the sea floor algae and plants? If fewer organisms are eating them, shouldn’t their numbers have increased? Why are they rare now?it is discovered that the algae-killing product (AlgaeBdead) that spilled in Lake Ontario also inhibits (slows) the growth of fungi in the lake. Explain one way this would negatively affect the lake ecosystem.Why would growing algae help reduce thecarbon footprint of a city or town?
