Scientists are studying the effects of climate change on the Baltic Sea. Some scientist predict that if current trends continue, the Baltic sea will become less salty, and it will contain less dissolved oxygen. As a result of theses changes, the Baltic Sea will have less biodiversity. The location of the Baltic Sea is shown on the map below. Which statement best explains why biodiversity in the Baltic Sea could decrease f these changes occur?

a)

Fewer types of plants and animals are found in warm water than in cool water.

b)

Plants and animals adapted for living in saltwater will grow more slowly in water that has less salt.

c)

Plants and animals adapted for living in saltier conditions will not be able to survive and reproduce.

The organism in the photo is Daphnia, or water flea. Daphnia are tiny aquatic organisms that live in most freshwater habitats. Adults range from less than 1 to 5 mm in length. They are good swimmers and eat mostly algae. Daphnia become mature at 5 to 10 days, and an adult female can produce up to 100 eggs every 3 or 4 days during its 2-month life span. When harmful algae rapidly increase in the Daphnia's environment, Daphnia can develop adaptations to tolerate the negative effects of the algae within 10 years. What characteristic of the Daphnia allows the population to adapt to environmental change?

a)

Its small size

b)

Its short generation time

c)

Its freshwater environment

d)

Its herbivorous diet
