Which statement correctly describes the diagram?
a) the products of photosynthesis cannot be used by other organisms.
b) the products of respiration can be used by plants for photosynthesis.
c) the exchange of oxygen and carbon dioxide occurs only in respiration.
d) the exchange of oxygen and carbon dioxide occurs only in photosynthesis.

B) The products of respiration can be used by plants for photosynthesis.

Explanation:

The product of respiration are water and carbon dioxide which are used by plants in photosynthesis and produce sugar and oxygen which are the reactants of respiration.

Respiration

It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Glucose + oxygen → carbon dioxide + water + 38ATP

Photosynthesis:

It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.

Carbon dioxide + water + energy →   glucose + oxygen

Chemical equation:

6H₂O + 6CO₂ + energy  →   C₆H₁₂O₆ + 6O₂

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
