Algae require warmth, sunlight, and nutrients to grow and reproduce, so they live in the upper 60 to 90 meters (200 to 300 feet) of ocean water. The upper layer of water, the epipelagic zone, is rich in oxygen, penetrated by sunlight, and warmer than water at lower levels.

Where do algae live and grow?

There are about 27,000 different species, or types, of algae. They are most common in water, such as oceans, rivers, lakes, streams, ponds, and marshes. Some species live in soil or on leaves, wood, and stones. Algae even grow on animals such as turtles and polar bears.

Where would most algae be found?

the sea

Most species of algae live in the sea, in lakes, or in ponds. Some single-celled green algae live in moist conditions on land, such as on tree trunks, on the surface of the soil, or on damp brickwork. Others live inside lichens.

Is there algae in the ocean?

In the ocean, microscopic forms of algae can “bloom” into dense patches near the surface, often referred to as “red tides.” Some of these harmful algal blooms (HABs) are dangerous, producing toxins that can kill marine organisms, taint shellfish, cause skin irritations, and even foul the air. HABs occur worldwide.

Is algae found at the bottom of the ocean?

Weʻre learning about algae that grows in deep sea environments, called mesophotic reefs. Beyond the reach of conventional scuba, mesophotic reefs receive just enough sunlight for algae to grow and photosynthesize. Deep sea corals, other invertebrates, and fishes also inhabit these remote environments.

Where do green algae live?


Habitat: Green algae can be found in all types of habitats including ponds, lakes, rivers and soil. Most greens prefer freshwater, but a few also grow in brackish and marine waters. Some freshwater filamentous greens can be found in fast moving currents attached to rocks and roots or simply floating on still waters.
