• Hetereotrophs transmform inorganic material into organic material.

• Heterotrophs get energy only from plants.

• Autotrophs get energy only from animals.

Answer explanation

Autotrophs transform inorganic material into organic material and make their own nutrients.

In Van Helmont experiment: After 5 years, what happened to the soil and the willow?

• The willow decreased and the soil increased.

• The willow decreased and the soil decreased

• The willow increased and the soil remain the same.

• The willow increased and the soil decreased.

What hypothesis was Van Helmont attempting to prove with his experiment?

• Plants get their nourishment from the air.

• Plants get their nourishment from photosyntesis.

• Plants get their nourishment only from water.

• Plants get their nourishment from minerals in the soil.

True or false: Photosyintesis and respiration are opposite processes.

• TRUE

• FALSE

Answer explanation

Photosynthesis consumes carbon dioxide and releases oxygen.

Respiration consumes oxygen and releases carbon dioxide.

In the process of photosynthesis, what would happen if there were no carbon dioxide?

• The oxygen would produce carbon dioxide,

• The plant will carry out this normally because of the presence of water.

• The glucose would produce carbon dioxide.

• Photosynthesis would stop because it requires this gas.

Answer explanation

The plant needs water, carbon dioxide and light to produce glucose and oxygen.
