The impact that the oil spill has is environmental impacts.
This question is more for Biology than Chemistry, but the role of producers is to make energy (food) to be consumed. In a pyramid diagram, the producers would be at the bottom. Now going up the pyramid, the primary conumers are the first to consume producers and obtain energy from them. As you go up the pyramid, the secondary consumers will consume the primary consumers as a way to obtain energy, and the same goes for tertiary consumers towards secondaries.
As you go up the energy pyramid, you will notice a trend that there is less energy being obtained from each consumer. In other words, the producers will ALWAYS have more energy than the tertiary consumers.
I hope this answers your question.

Hi!
In this reaction, the chemical energy of of the products ( C2H4 & H2 ) are greater than the chemical energy of the reactant ( C2H6 ).
We can see this by the value of the change of enthalpy in the system which in this given reaction is +137 kJ.
The positive enthalpy change indicates that the energy invested in the reaction is more than the energy released, which means that the system has absorbed energy. This is often translated as the products being at a higher level of energy as compared to the products.
This is an example of an endothermic reaction, and you can develop a better understanding by referring to the attached picture.
Hope this helps!
