The question is incomplete as it does not have the answer which are:
A) They do not participate in the Calvin cycle.
B) They use PEP carboxylase to initially fix CO2.
C) They conserve water more efficiently.
D) They exclude oxygen from their tissues.
Answer:
They use PEP carboxylase to initially fix CO2.
Explanation:
Photorespiration is a wasteful process in plants which produces less amount of ATP and low glucose level as the RUBISCO enzyme binds with the oxygen instead of Carbon dioxide.
The Rubisco enzyme binds with the carbon dioxide usually during the Calvin cycle but in hot and dry conditions it binds the oxygen.
So to avoid the photorespiration, plants evolved adaptive features in the anatomy of the leaf that is they separated the photosynthetic steps by forming wreath-like structure around the vascular bundles called Kranz anatomy.
Instead of Rubisco, PEP carboxylase binds the carbon dioxide, convert it to malate and then transport it to bundle sheath cell where the Calvin cycle takes place as malate provide Carbon dioxide gas to Rubisco enzyme.
Thus, the selected option is correct.

Answer:
b. water depth
Explanation:
The abiotic factors are the factors that are not part of the biosphere, thus they are not living organisms. In this case, the water depth is that type of factor that would influence the marine ecosystems. The depth of the water is crucial for the type of organisms that can exist in it, their density, and diversity. This is because the water has certain characteristics that provide certain conditions, like if the water is shallow, it will be warmer, but if its deep, then it will be colder. The amount of nutrients in it also depends on the depth. The sunlight can penetrate into the water only in the shallow parts, but not in the deep ones, so the basis of the ecosystems, the producers can exist only where they can have sunlight to perform the process of photosynthesis.
I’m pretty sure the answer is the third choice
