Question
Chapter 28, Problem 2COQ
Summary Introduction
To explain: The way in which a hypothesis “two macroalgae might be from different generations of the same species that have different optimal temperature” can be tested.
Introduction: A group of marine biologist discovered two new types of macroalgae. However, they hypothesized that these two discovered macroalgae belong to the same species. They stated that these macroalgae occur during a particular period of the year. This was due to their different optimal environmental conditions.

Climate 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?
Protists, mostly those that live in the ocean, perform approximately half of the photosynthesis on Earth. How might their large role in the carbon cycle impact climate change?

- You have two identical bags and fill them with the same amount and type of leaves. You put the identical bags in two different areas of a river. After several weeks, one set of leaves has almost disappeared and the bag is full of organisms. The other set of leaves is still mostly whole and the bag has few organisms in it. Questions: What are some ways the two different areas of the river could be different? How might these differences explain why the leaf packs in one area have more organisms than the leaf packs in another area?arrow_forwardA re-created ecosystem in a laboratory environment is known as a ________. a. mesocosm b. simulation c. microcosm d. reproductionarrow_forwardFocusing just on the effects of temperature, would you expect the global distribution of C4 plants to expand or contract as Earth becomes warmer?
