Answer:
The correct answer is a hypothesis.
Answer:
Eating contributes to the flow of an ecosystem because in a food web/chain, there is always a consumer. Starting from the very bottom of the food web/chain, all organisms eat to pass on the energy to the next cosumer. For example, a grasshopper eats some grass. That grass is made into energy. Then, a possum eats that grasshopper, the energy from the grasshopper converting to the energy of the possum. Then a giant snake comes along and eats the possum. The energy keeps flowing up and up the food chain as animals consume(and be consumed).

Answer: Option C.
<u>Explanation:</u>
The water particle is very simple and basic. A particle is a bit of issue that contains at least two iotas. The logical name for water is H2O. It is called H2O since it has two iotas of hydrogen (H) and one molecule of oxygen (O). There are a great many these atoms in a single drop of water.
A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen.
