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*
A. there is a change in Genetic frequency
we know automatically that glucose and pyruvate are wrong answers due to the fact that glucose is sugar and that pyruvate is a type of acid. this just leaves us with ADP and ATP now ADP and ATP are very close answers, since ADP is what makes ATP, but an electron transport change usually involves the transfer of electrons well if we look at their chemical formulas, we can see that ATP has more 1 more oxygen than ADP, and this kind of chain usually adds additional oxygen which gives us ATP as our answer.
