<h2>Answer:</h2>
saprotrophs or saprophyte
<h2>Explanation:</h2>
A saprophyte or saprotroph is an organism which gets its energy from dead and decaying organic matter. This may be decaying pieces of plants or animals. They are consumers in the food chain.Bacteria and fungi are important saprotrophs.
Attached are two images concerning DNA.
The first image is a diagram that illustrates the base paring of DNA. First, there is the ribose-phosphate backbone that keeps the DNA together. Then the bases thymine and adenine are joined together by two hydrogen bonds. On the other hand, the bases guanine and cytosine are joined together by three hydrogen bonds.
The second image shows the helical structure of the DNA.
<span>Damming a river has a variety of effects on the freshwater ecosystem, more than just altering the flow from A to B. Dams create calm bodies of water, changing overall temperature regimes and sediment transport, leading to conditions which tend to favour generalist species. Loss of specialist species, particularly endemics, changes the community structure and leads to biotic homogenization. A dam will withhold sediment in the reservoir, not just decreasing the amount of substrate available to local freshwater species, but even impacting diadromous, estuarine and marine species much further downstream. The competition between resident species for food and breeding sites will increase as damming isolates populations, and perhaps more importantly, damming completely restricts migratory fish species. Isolation may lead to decreases in genetic diversity and therefore puts species at greater risk from disease. All of these effects may be exacerbated by changes in the surrounding land use. Overall, damming river flow will lead to both a loss of native species, but also an increase in exotic species which are more likely to become established in degraded habitats. For this reason, dams are one of the greatest global threats to freshwater biodiversity.</span>
Data about stars in our universe is obtained by mean of telescopes.
<h3>What is a star?</h3>
A star is a large luminous astronomical body which produces light and heat energy as well as radiation.
There are billions of stars in the universe organized into galaxies.
The Sun is the star of our solar system.
In the video, a mysterious star was observed which is 50 percent bigger and 1,000 degrees hotter than the Sun.
By mean of telescopes, it was observed that the dimming seen in the diet was dues to dust particles.
