Molecular compound; Molecule
CO2 is an example of a molecular compound or molecule.
A molecule is the smallest particle of a specific element or compound that retains the chemical properties of that element. Molecules are composed of two or more atoms that are joined together by chemical bonds. Molecules may be simple or complex.

Answer:
Energy from the sun light
Explanation:
This happens directly or indirectly.
Producers use this energy directly to make organic material, via photosynthesis, that gets passed down the food chain. Herbivores and other organisms will get this energy indirectly by eating the organic material made by the producers using this light energy.
So all the organisms someway get their energy from the sun light.
C) To gather info about the natural world, to explain natural phenomena, and allow reasonable predictions of future events
Answer:
Inspiration (breathing in)
The diaphragm contracts and moves downwards. The intercostal muscles contract and move the ribs upwards and outwards. This increases the size of the chest and decreases the air pressure inside it which sucks air into the lungs. During normal breathing, the major inspiratory muscles produce rib cage expansion and a downward movement of the diaphragm. These movements cause the pressure around and in the lung to become negative (relative to atmospheric pressure).
