Question

For what reason cyanobacteria are often called the first colonizers of moist soils

Answer 1

Answer:

Cyanobacteria are also very successful primary colonizers in terrestrial habitats due to their tolerance of desiccation and to water stress. ... As they bind sand and soil particles, cyanobacteria prevent erosion. They help to maintain moisture in the soil and contribute nitrogen to it through nitrogen fixation.

Answer 2

Cyanobacteria, also known as blue-green algae, are microscopic photosynthetic organisms that are technically bacteria.

Cyanobacteria:

• Cyanobacteria, also known as Cyanophyta, are a Gram-negative bacteria phylum that obtains energy through photosynthesis.
• Cyanobacteria are aquatic and photosynthetic, which means they live in water and can produce their own food.
• Because they are bacteria, they are small and usually unicellular, though they frequently grow in visible colonies.
• As a result of oxygenic photosynthesis, cyanobacteria are responsible for the Earth's transition from a carbon dioxide-rich atmosphere to a current relatively oxygen-rich atmosphere.
• Cyanobacteria can be found all over the world, including in harsh environments such as deserts and hot springs.
• Lichen is made up of fungus and cyanobacteria and grows on rocks and trees.
• Spirulina tablets are a dietary supplement made from two cyanobacteria species.
