Aquatic Systems

Phytoplankton are too small to be seen with the naked eye. They obtain energy through photosynthesis. They account for half of the photosynthetic activity on earth.

Zooplankton are a heterotrophic type of plankton. They live in salt and fresh water. They are able to move around by a process called Diel vertical migration.

Aquatic macrophytes are plants that grow in or near water. They can provide shelter as well as a food source for fish. Macrophytes also produce oxygen.

Gold fish are the most common fish kept in aquariums. They were first domesticated in China over a thousand years ago. Gold fish breeds vary in shape, size, and color.

King crabs are known as a super family of the decapod crustaceans. The red king crab is caught and sold for food.

Mitochondrial Eve

In the field of human genetics, Mitochondrial Eve refers to the most recent common matrilineal ancestor from whom all livinghumans are descended. Passed down from mother to offspring, all mitochondrial DNA (mtDNA) in every living person is directly descended from hers. Mitochondrial Eve is the female counterpart of Y-chromosomal Adam, the patrilineal most recent common ancestor, although they lived thousands of years apart.
