Answer:
<u>Mainly there are four different types of Trophic levels in an ecosystem. </u>
Explanation:
<u>Trophic level: </u>In biology, the term "trophic level" is described as a specific group of different organisms within a particular "ecosystem" that tends to occupy a similar level of a "food chain".
There are four distinct types or levels of trophic levels in a specific ecosystem:
1. Algae and plants produce their food by their own and are referred to as <u>"producers".</u>
2. Herbivores generally eat plants and are referred to as <u>"primary consumers".</u>
3. Carnivores that tends to eat herbivores are referred to as <u>"secondary consumers".</u>
4. Carnivores that tend to eat other carnivores are referred to as<u> "tertiary consumers".</u>

Answer:
D. Enzymes open the DNA strand, remove a segment of DNA from the strand that contains the damage, and resynthesize the correct DNA sequence.
Explanation:
From time to time, the DNA gets exposed to certain chemicals or radiation that damages it. However, the cell has a DNA repair mechanism in place called NUCLEOTIDE EXCISION REPAIR (NER).
NUCLEOTIDE EXCISION REPAIR (NER) is one of the DNA repair mechanisms in which certain enzymes open the DNA strand, remove a segment of DNA that contains the damaged gene or nucleotide bases, and resynthesize the correct DNA sequence using the pair of the damaged one.
