Why is the transparency of water so biologically important?

water is transparent which allows light to filter into aquatic environments, thus aquatic plants can absorb light and perform photosynthesis.


What is an one-cell organism?

An ameoba is a unicellular (one-celled) organism. It is commonly found in aquatic environments, and can cause disease.


Are fungi photoautotrophs?

False, chemoheterotrophs


What is the difference between terrestrial biome and aquatic biome?

Differences between Terrestrial and Aquatic systemsbecause aquatic environments are so rich in nutrients they support more live than equivalent terrestrial ecosystems. The small drifting photosynthetic organisms of the oceans, referred to collectively as phytoplankton are regarded as the major photosynthesizers, or primary producers, of the earth,aquatic environments are much more stable than terrestrial environments, with smaller fluctuations in temperature and other variables,aquatic organisms are seldom exposed to desiccationwhile terrestrial organisms are often exposed to desiccation and are usually relatively resistant to drying out,oxygen (because there is very much less present) is sometimes a limiting factor an aquatic habitats but this is seldom the case in terrestrial habitats,light can be a limiting factor in some aquatic habitats, but in most terrestrial environments there is hardly ever a a shortage of light,terrestrial animals are influenced far more by gravity, while water supports aquatic organisms.


What are the differences between autochthonous and allochthonous microorganisms in aquatic environments?

Autochthonous microorganisms are primary producers (create own energy, for example, through photosynthesis. Allochthonous microorganisms get energy from outside sources.
