Answer:

Description below

Explanation:

Alcionaceans (Alcyonacea) is an order of corals that belongs to the subclass Octocorallia, of the Anthozoa class. <em>Soft corals</em> are commonly called, since they do not produce skeletons of calcium carbonate, so they do not contribute to the construction of the reefs, although they inhabit them.

The so-called soft corals and leather or leather corals, mostly meaty in appearance, have microscopic crystals of calcite in their tissues called spicules, whose function is to give consistency to the animal's tissue, in the absence of a skeleton. The shape and distribution of the spicules are the main characteristics used in the identification of genera and species of octocorals.

In addition to soft corals, this order includes gorgonians, which replace the skeleton of hard corals, Scleractinia order, by semi-rigid structures composed of calcite and / or a substance they generate called gorgonin.

Answer:

Rowan's correct way to describe soft corals is by saying, "Soft corals are a species of coral that have no internal calcium carbonate skeleton."

Explanation:

Soft corals are a group of coelenterates that are characterized by not having an internal calcium carbonate skeleton. They form colorful coral reefs, especially in tropical waters.

These marine invertebrates belong to the order Alcyonacea, which, in turn, includes two groups: the true soft corals, or sea feathers, and the gorgonians, or sea fans, consisting of an internal protein axis.

Unlike hard corals, true soft corals rely on skeletal elements called sclerites. These calcified spicules ensure support and firmness, as well as a spiny texture that aids in their defense.

Readme [11.4K]

Answer:

Damaged the marine organisms.

Explanation:

The oil released offshore causes damaged to the organisms lives at that region of water because oil is a non-polar solvent which spreads on the sea flood can adversely affected the fish and other aquatic organisms. The resources which are available to the organisms are decreases which leads to lowers the growth of aquatic animals as well as adversely affected the marine ecosystem near or around the sea shore.

Species richness increases Select one: a. as we increase in altitude in equatorial mountains. b. as community size decreases. c.
olga55 [171]

Answer:

D) as we travel southward from the North Pole.

Explanation:

Species richness is the number of different species in a particular community. If we found 30 species in one community, and 300 species in another, the second community would have much higher species richness than the first.

Communities with the highest species richness tend to be found in areas near the equator, which have lots of solar energy (supporting high primary productivity), warm temperatures, large amounts of rainfall, and little seasonal change. Communities with the lowest species richness lie near the poles, which get less solar energy and are colder, drier, and less amenable to life. This pattern is illustrated below for mammalian species richness (species richness calculated only for mammal species, not for all species). Many other factors in addition to latitude can also affect a community's species-richness.
