Coral reefs have the highest biodiversity of any marine ecosystem on Earth. Hundreds of plant and animal species live in close association with the coral in these reefs and depend on them for survival.

In recent years, global climate changes have slowly begun to increase the temperatures of the ocean. Coral are very sensitive to temperature changes—even an increase of 0.5°C can cause them to bleach and die.

A scientist is making a graph to predict how the biodiversity of coral reefs will change if global temperatures continue to increase. This graph will most likely show
A.
that the diverse species of the coral reef will move from marine ecosystems into land ecosystems.
B.
that the biodiversity of the coral reefs will decrease if global temperatures continue to increase.
C.
that the biodiversity of the coral reefs will not change if global temperatures continue to increase.
D.
that the biodiversity of the coral reefs will increase if global temperatures continue to increase.

B.

that the biodiversity of the coral reefs will decrease if global temperatures continue to increase.

Explanation:

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than twenty-five percent of marine life.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
