Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species <em>could </em>lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.
I hope this helps. Have a great week!

Answer: change from one form of energy to another
Explanation:
As the name implies, Energy transformation refers to the conversion of one form of energy to another, such that energy is always conserved.
For instance:
- an electric pressing iron convert electrical energy to heat energy;
- a solar panel convert solar energy to electrical energy etc
All these are examples of energy transformation in nature.
