3. Several species of fish live in the same area within a coral reef. Some hide among corals and filter passing plankton, others actively chase and eat smaller fish, and still others nibble on the coral. Based on the differences among these species, which of these would you predict is the main cause of the various “occupations” represented by the fish in the coral-reef ecosystem? А population sizes B limited food resources C adaptations that determine niches D environmental conditions that result in crowding​

A fossil of a different species is found that has none of the characteristics shared by species X and species Y.
C.
A third living species is found that has none of the characteristics shared by species X and species Y.
D.
A third living species is found that has some of the characteristics shared by species X and species Y.

Increasing sea surface temperatures should.

Lower the amount of dissolved oxygen in the ocean, depriving many
invertebrate animals of oxygen necessary to live.
Lower the amount of sea ice in polar areas. This will warm the water,
decreasing the abundance of primary producers and the number of
organisms that eat these producers.
Increase the temperature difference between the upper and lower parts of
the ocean, making upwelling less likely to occur. This will decrease ocean
nutrient levels, affecting the number of primary producers.
Raise water temperatures above the tolerance limits for many aquatic
organisms in tropical areas, increasing stress on these species.
