<u>Answer:</u>
<em>The genetic instructions are found in </em><u><em>the nitrogen bases </em></u><em>within the DNA, which is contained in </em><u><em>nucleotide</em></u><em> inside the nucleus of the cells. </em>
<u>Explanation:</u>
Inside nucleotide there are nitrogen bases along with phosphate group and sugar group. The four nitrogen bases are <em>adenine, thymine, guanine and cytosine (ATGC). </em>
These four bases pair up with each other inside the nucleotide. The order in which these bases are placed determines the genetic codes. This passes the instructions and characteristics from the parents to offspring.

Trophic levels can be represented by numbers, starting at level 1
with plants. Further trophic levels are numbered subsequently according
to how far the organism is along the food chain.
Level 1: Plants and algae make their own food and are called primary producers.Level 2: Herbivores eat plants and are called primary consumers.Level 3: Carnivores that eat herbivores are called secondary consumers.Level 4: Carnivores that eat other carnivores are called tertiary consumers.Level 5: Apex predators that have no predators are at the top of the food chain.*Hope that helps XD*
