Question

1. why do phytoplankton live near the surface?
2. what tiny animals eat phytoplankton?

a. zooplankton
b. sharks
c. sea turtles

1. through what process do zooplankton return co₂ to the ocean?
2. some phytoplankton die and ______________ to deeper water.
3. put the steps of the biological pump process in order based on the video (1-6):

order (1-6) process steps
a. clumps + fecal pellets sink
b. uneaten phytoplankton clump + die
c. deep animals eat material + release co₂
d. zooplankton graze on them
e. phytoplankton grow + reproduce
f. phytoplankton take in co₂

1. what do deep-ocean animals do with sinking particles?

a. eat them for energy
b. ignore them
c. turn them into shells

1. deep animals release ______________ back into the water.
2. when deep water rises (upwelling), what does it bring up?

a. sand
b. oil
c. co₂

1. the ______________ warms rising water and causes more co₂ to escape.
2. what tool do scientists use to collect sinking particles?

a. sediment traps
b. nets
c. magnets

1. sediment traps collect falling ______________.
2. what is the big idea you learned from this video about how carbon moves through the ocean in 2-3 sentences.

you can use one of these optional sentence starters to begin to construct your answer:

• the big idea of the video is that carbon...
• the ocean affects carbon by...
• carbon moves when...

Explanation:

1. Phytoplankton are photosynthetic organisms that require sunlight to produce energy, so they live near the sunlit surface.
2. Zooplankton are small aquatic animals that feed directly on phytoplankton, while sharks and sea turtles are larger consumers that do not target tiny phytoplankton.
3. Zooplankton perform cellular respiration, which breaks down organic matter[LLM SSE On Failure]

Answer:

1. They need sunlight for photosynthesis.
2. A. Zooplankton
3. Respiration
4. Sink
5. 1. F; 2. E; 3. D; 4. B; 5. A; 6. C
6. A. Eat them for energy
7. CO₂ (carbon dioxide)
8. C. CO₂
9. Sun
10. A. Sediment traps
11. Organic particles/carbon-rich material
12. The big idea of the video is that carbon moves through the ocean via the Biological Pump: phytoplankton take in surface CO₂, are consumed or die, sink as organic matter, are broken down by deep-ocean organisms, and released CO₂ is eventually brought back to the surface via upwelling, creating a continuous carbon cycle.
