Why are photosnthetic organisms found in shallow water?

photosynthetic organisms are found mainly in shallow water due to the availability of this. ... Because water absorbs light, sunlight that is usable by plants for photosynthesis penetrates only about 100 m into the ocean.

Where are all photosynthetic organisms found in the water and why?

They live in various habitats including salt and freshwater aquatic environments, wet soil, or on moist rocks. Photosynthetic algae known as phytoplankton are found in both marine and freshwater environments. Most marine phytoplankton are composed of diatoms and dinoflagellates.

Which layer of the water contains photosynthetic organisms?

The photic zone, euphotic zone, epipelagic zone, or sunlight zone is the uppermost layer of a body of water that receives sunlight, allowing phytoplankton to perform photosynthesis. It undergoes a series of physical, chemical, and biological processes that supply nutrients into the upper water column.

What regions do you find photosynthetic organisms?

In which of the following regions would you expect to find photosynthetic organisms? The aphotic zone, the neritic zone, the oceanic zone, and the benthic realm. The photic zone, the intertidal zone, the neritic zone, and the oceanic zone. The photic zone, the abyssal zone, the neritic zone, and the oceanic zone.

In what zones of the lake should you find photosynthetic organisms?

Unlike the profundal zone, the limnetic zone is the layer that receives sufficient sunlight, allowing for photosynthesis. For this reason, it is often simply referred to as the photic zone. The limnetic zone is the most photosynthetically-active zone of a lake since it is the primary habitat for planktonic species.

What do photosynthetic organisms do?

Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.

What do photosynthetic organisms have in common?

All photosynthetic organisms contain a pigment called chlorophyll a, which humans see as the common green color associated with plants. Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green. Because green is reflected, chlorophyll appears green.

Why is Prochlorococcus important?

Despite Prochlorococcus being one of the smallest types of marine phytoplankton/bacteria in the world's oceans, its substantial number makes it responsible for a major part of the oceans' and world's photosynthesis and oxygen production.

What is the shallow near shore part of the photic zone called?

These organisms are called the benthos, and their habitat is the benthic zone. When the water is shallow enough for the benthic zone to be within the photic zone, algae and rooted aquatic plants can grow. When the benthic zone is below the photic zone, chemosynthetic autotrophs are the only primary producers.

Where in the ocean would there be no photosynthetic organisms found?

At depths greater than 200 m, light cannot penetrate; thus, this is referred to as the aphotic zone. The majority of the ocean is aphotic and lacks sufficient light for photosynthesis.

How does photosynthesis occur in the sea?

Just like plants on land, ocean-going plankton need light from the sun to prosper and grow. But light is absorbed by ocean water -- and some colors of light are absorbed more readily than others. ... That's why nearly all photosynthesis in the ocean takes place in the sunlit upper layers.

Do aquatic ecosystems need sunlight Why or why not?

Do aquatic ecosystems need sunlight? Of course. ... Sunlight, of course, is necessary for photosynthesis, which brings energy into an ecosystem. So, the availability of that sunlight has a direct impact on the productivity and biodiversity of aquatic ecosystems.

Where are the most photosynthetic cells in plants found?

Photosynthetic cells are found mainly in the leaves of plants and may have thousands of chloroplasts. Chloroplasts are double-membrane organelles with a smooth outer membrane and an inner membrane folded into disk-shaped sacs called thylakoids.

What factors determine aquatic biomes?

Abiotic factors that influence aquatic biomes include light availability, depth, stratification, temperature, currents, and tides.

Why are aquatic biomes important?

Like terrestrial biomes, aquatic biomes are influenced by a series of abiotic factors. The aquatic medium—water— has different physical and chemical properties than air, however. ... The importance of light in aquatic biomes is central to the communities of organisms found in both freshwater and marine ecosystems.

How does the coastal ocean zone compare with the open ocean zone?

Even though the coast is just a small sliver of the ocean, it is the more productive of the two marine biomes. This means the coasts hold more marine biodiversity, which provides food for many animals, including humans. The open ocean stretches from the edges of the coast between the continents for hundreds of miles.
