Answer:
TRUE
Explanation:
The answer is True.
A spaceship designed to support animal life which is set out to the outer planets of the solar system for a voyage for many years.
It seems that plants will grow inside the spaceship to provide oxygen and to recycle carbon dioxide. But because the spaceship will travel too far from the sun, the plant will need an artificial light source for photosynthesis to take place.
In order to maximize plant growth with a minimum of energy expenditure, the wavelength mixture of blue and red light should be used.
Thus the answer is True.
