Answer;

A) Stage 1: Chlorophyll captures light energy. Stage 2: Light energy is converted to chemical energy.

Explanation;

-Photosynthesis is the process by which green plants use energy from the sun, water and carbon dioxide to make organic compounds such as simple sugars together with release of oxygen.

-The process occurs in tow stages; light-dependent stage and light independent stage. During light dependent stage, chlorophyll absorbs sunlight and uses it to split water molecules into hydrogen ions and oxygen atoms. In the light independent stage carbon (iv) dioxide is fixed and the result is organic compound; the light energy is converted to chemical energy.

Why does the black carbon ball have 4 holes while the white hydrogen ball only has one hole?

ryzh [129]

In atomic models balls represent an atom

Now if an atom like carbon has four holes it means it can bond with four atoms. It has valency = 4.

The atomic number of carbon is 6

the configuration is 1s2 2s2 2p2

So due to four valence electrons it can bind with four other atoms and thus we have four holes in carbon ball

The hydrogen show a valency of one

the atomic number of hydrogen = 1
