Viruses are not considered living organisms because they lack some of the basic characteristics of life.
The cell is described as the smallest unit of life. Since viruses are <u>not alive</u>, we can infer that they <u>do not </u>contain one or more cells. <u>Viruses </u>have a <u>protective</u> <u>protein coat</u>, which can be considered a defined boundary.
Viruses are not capable of producing or using their own energy. They only activate when they come into contact with a host cell and <u>then use the host cell's energy. </u>
As per the pattern, viruses<u> </u><u>do not have</u> internal organization nor metabolic processes which would allow for growth, therefore, viruses do not grow nor do they produce waste in any form.

Changes of abiotic factors can have a huge influence on living organisms of ecosystem. The effects might be benefical or harmful.
Some of the most common abiotic factors that can impact a marine ecosystem are water temperature, currents, light, alkalinity, oxygent concentration etc.
