Answer:

c. have changed the behavior of elk.

Explanation:

Wolves were reintroduced into Yellowstone Park in 1995. Prior to this time, they were a major predator in the park. Their reintroduction after a decade resulted in a change in the behavior of the Elk which now had a large population in the park and appeared in large herds.

The Elk's behavior has also changed as they do not move into farther thickets so as not to be attacked by wolves. Also, they no longer move to open fields where they grazed as herds to avoid being preyed upon by lions. Vegetation is now restored due to this change in behavior of the Elk.

Elodia [21]

Answer:

c.) loss of chloroplasts

Explanation:

Chloroplasts are the double membrane-bound organelles of photosynthetic eukaryotes and serve as the site for photosynthesis. The organisms that can carry out photosynthesis make the organic nutrients and do not depend on other organisms for food.

According to the given information, the photosynthetic protists become parasite in fish and start deriving nutrition from the host. If the protists continue to survive as a parasite to fish, the chloroplasts will be rendered non-significant. The parasitic mode of nutrition does not require chloroplasts and therefore, the protists would lose the organelles over generations.
