Answer and Explanation:
Corals are translucid or white, but they look brightly colored because they host symbionts with colorful photosynthetic pigments
. They can host different organisms that live on and among them, giving place to an amazing ecosystem.
One of these organisms is the photosynthetic unicellular microalgae, called zooxanteles, that are colorful and provide nutrients to the coral.
Corals provide shelter and protection to the algae, while algae provide nitrogenated nutrients, sugars, and color to the corals. Algae can store nitrogen in their tissues as nitrogen-rich crystals, which are constantly provided to corals.
This symbiotic relation allows corals to grow in different environments that are poor in nitrogen or other nutrients, such as the tropical clear waters.
When changes in radiation, temperature, or salinity in water occur, corals react to these changes losing these algae and becoming translucid again.
<span>This result is produced by the selective permeability of the plasma membrane when the presence of negatively charged ions does not diffuse into the cell and the action of several sodium-potassium pump units causes an unequal distribution of charges through the membrane.</span>
The three ways or approaches that one can do to slow down
extinction or in a way to preserve biodiversity are the following;
-
Breeding endangered species that may preserve
and multiply their species
-
Protecting the endangered species in a way that
they should not be held captive, be sold or kill for materialistic goods or
food products
-
Prevention of using animal testing in factories
and companies
<span>Numerous ecosystems systems can exist in one biome in light of the fact that a biome is immense, and take the Marine Biome for example.There are diverse zones that things live in or environments. There are environments appropriate by the shore, somewhat more distant, and one ideal amidst the water. So there can be numerous in one biome in light of the fact that a biome is only one class, similar to tundra, or marine.</span>
