The ocean has many different ecosystems, or communities of living organisms and their environment. Life in the ocean is more diverse and plentiful than on land. In fact, the very first life on Earth, a microscopic single-celled organism, probably started in the ocean 3.5 billion years ago.

About 80% of all marine organisms live in the euphotic zone. This is the top layer of the ocean, from the water’s surface down to about 100 meters. The euphotic zone is also known as the sunlit zone. It gets enough light for plants to undergo photosynthesis, or convert the sun’s energy into food. It contains vibrant ecosystems such as coral reefs, mangroves, kelp forests, and estuaries. Food and shelter are plentiful in the euphotic zone, which is home to most ocean fish, jellyfish, sea turtles, seals, coral, starfish, and shellfish.

Why is marine life so plentiful in the euphotic zone?

A
This zone is at the very bottom of the ocean, so fish can absorb minerals from the sand.

B
This zone provides enough light, food, and shelter to support a wide variety of organisms.

C
This zone is home to all plants and animals that do not need sunlight to survive.

D
This zone is used as farmland, growing crops that fish and other sea organisms eat.

Which of the following statements is true?

(A) Mutation is the only way to vary the gene pool in a population that reproduces by sexual reproduction.

(B) Fewer harmful mutations are inherited by sexual reproduction than by asexual reproduction.

(C) Sexual reproduction is faster than asexual reproduction.

(D) Offspring from asexual reproduction have more genetic variety than offspring from sexual reproduction.

The ocean is one of Earth’s biomes. A biome is an area that is characterized by the plants and animals that live there. There are five major oceans—the Atlantic, Pacific, Indian, Arctic, and Southern—that are all connected in what is known as the World Ocean. The ocean, sometimes called the marine biome, is huge, covering 70% of the Earth’s surface. However, humans have only explored about 5% of it. Scientists know less about the ocean than they do about the dark side of the moon. In this way, the ocean is considered the Earth’s final frontier.

Which of the following is true?

A
The Atlantic, Pacific, Indian, Arctic, and Southern Oceans are completely separate from each other.

B
The ocean covers about half of the Earth’s surface.

C
Scientists have studied most of the ocean, but a tiny bit remains unexplored.

D
Scientists know more about the moon than they do the ocean.
