Answer:
Explanation:
For part C, this should be what the graph looks like.
The reactants should have higher energy that the products so that it can release energy. Recall the reaction is N2 + 3H2 => 2NH3 + energy, making it exothermic. Apparently, you are supposed to adjust the energy diagram on the simulation so that 20% of the reactants become the products.
The answer is b. as a whole, the species is mutually beneficial to carry on each others traits and exist in the same ecosystem.
