Tenth Place: Microscopic Carbon Sinks

The connection between organisms and a healthy ecosystem is seen at the microscopic level in this picture of Actinocyclus diatoms (circular shapes, above) and the red seaweed Antithamionella. The life-forms rely on each other for survival, photographer Arlene Wechezak said in a statement.

In addition, the two marine plants act as carbon dioxide sinks, and thereby "play an important role in maintaining the Earth's climate," added Wechezak, a retired cell biologist Arlene Wechezak from Washington State.
