6. It’s pointing to the Cell wall. The cell wall protects the cell so A is correct
7. B is correct, prokaryotes don’t have a nucleus
8. A is correct plant cells only have a chloroplast
9. I would say D
10. I would say A
Hope this helps

The answer for this one is B. I hope I help! :)
Answer:
C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.
Explanation:
The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.
Why not the other answers:
A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.
The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.
B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.
D) Wading birds were never eaten by ospreys. There is no arrow connecting them.
Light is absorbed by photosynthesis. The light rays are then trapped inside the lumen, in the photosystems. Then through conversion processes (calvin cycle), the plant produces glucose and gives off O2
