Topic 1.8 - College Board Videos to Watch

Go to: https://apclassroom.collegeboard.org/d/1ot2e3nnir?sui=14,1 to watch Topic 1.8 Daily Video 1 which explains how primary productivity is the rate at which solar energy (sunlight) is converted into organic compounds via photosynthesis over a unit of time.

Go to: https://apclassroom.collegeboard.org/d/zjhjrdef8s?sui=14,1 to watch Topic 1.8 Daily Video 2 which compares the primary productivity of biomes.

Go to: https://apclassroom.collegeboard.org/d/w3eh3545ld?sui=14,1 to watch Topic 1.8 Daily Video 3 which introduces an investigation question of how to measure solar energy that is acquired and transferred by living organisms.

Take notes on these videos that summarize important key points. Focus your notes not just on content, but also how you are going to demonstrate you mastery of the content using science practices. Be sure to answer and questions that are asked when you pause the video. Check your answers!

APES

After watching this video can you answer the following questions?

1. Where does the energy ultimately come from that powers the bodies of living organisms here on Earth? How does the energy get into our food?

2. What role do producers play in primary productivity? What is biomass? What ingredients are needed to make biomass?

3. How much of the energy that reaches the Earth is used in photosynthesis, what happens to the rest?

4. Explain what GPP is. What is NPP? Why is NPP less than GPP?

Plant Productivity in a Warming World

After watching this video can you answer the following questions?

1. Plant grown can benefit from warmer temperatures and increased precipitation up to a point. What have we discovered about climate change and plants?

2. How is NPP studied by satellites? Why should scientists study primary production?

3. Where does the extra carbon dioxide come from that is contributing to climate change? Why do trees need carbon dioxide?

APES Unit 1.8 Primary Productivity

After watching this video can you answer the following questions?

1. Compare gross primary productivity and net primary productivity.

2. What biomes have the largest NPP? Which have the lowest NPP?

3. How are different wavelengths of light absorbed in the ocean? What does this affect?
