Im pretty sure its d, but im not sure
Still create mor which is called celluar respiration
No, since it is an island separate from the mainland Ecuador and has been uniquely isolated over the past several hundred thousand years, the species on the Galapagos Islands have had time to evolve differently and separately than those in Ecuador, leading to many different, diverse species on the Galapagos that don't exist in Ecuador
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
It could be over run with the minor consumers and such causing massive problems
