As true pressure we denote the absolute pressure. <span>
Gauge pressure is the pressure above the ambient pressure </span>(it is zero-referenced against ambient air pressure). Absolute pressure <span> is equal to gauge pressure plus atmospheric pressure.</span>So, according to this the gauge pressure is always less than the absolute pressure.
The sugar-phosphate backbone is an important structural component of DNA. It consists of 5-carbon deoxyribose sugars<span> and </span>phosphate<span> groups.

Answer:
The Rhizaria are supergroup species of mostly unicellular eukaryotes and classified as protista. Rhizaria include species like cercozoa, foraminifera and radiolaria.
<u>Some of the attributes of Rhizaria are:</u>
- non-photosynthethic in nature, but some have a symbiotic relationship with unicellular algae.
- express only rDNA sequences so they can vary in different forms.
- do not have clear morphological characters
- they mostly includes amoebas which functions for food engulfing and help to direct movement in rhizarian protista.
<u>Contribution of Rhizaria to the ecosystem:</u>
- There are known as abundant bacterial grazers, and play very important role in microbial food webs.
- They provide a wide diversity of marine organisms.
- important contributors to oceanic carbon pools .
Hence, Rhizaria are important part of ecosystem.
