The viruses are organisms

Virus is a microscopic particle that can infect the cells of a biological organism.

Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.

At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.

They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).

A virus that infects bacteria is known as a bacteriophage, often shortened to phage.

The study of viruses is known as virology, and those who study viruses are known as virologists.

It has been argued extensively whether viruses are living organisms.

Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.

They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.

A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.

Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.

Serious diseases such as Ebola, AIDS, bird flu and SARS are all also caused by viruses.

Select the best answer that describes how lionfish are impacting biodiversity in Florida. O Lionfish are consuming large quantit
jolli1 [7]

Answer:

Lionfish are rapidly consuming many smaller fish species along the coast at depths up to 90 meters.

Explanation:

Lionfish is an invasive species that has been successfully established in the Atlantic Ocean. It is a tropical species that lives mostly in reefs and rocks that provide protection. It <u>i</u><u>nhabits waters from the coast to 50 meters deep. </u>

Because of its high densities in the Atlantic, Lionfish is a promoter of ecological, economic, socio-cultural consequences. They only have a few predators and consume a high diversity of prey items. They produce an ecological imbalance in the trophic chains of the marine ecosystem. When competing with native piscivores, they imbalance the dynamics of fish communities in coral reefs and mangroves. The <u>density of young and herbivores fishes has decreased because of their predation by the lionfish</u><u>.</u> By <u>predating on algae eating fishes</u>, they provoke a sharp increase in algae populations, which produces serious damages in the coral reefs, enhancing their mortality. The main consequences of these damages are marine biodiversity loss, water quality decrease, ecosystem recovery difficulty, and impacts on food provisioning for many other ocean species.
