Question

A) Elysia chlorotica will die if not exposed to light
B) Elysia Chlorotica grows when exposed to light in the absence of other food sources
C) Elysia chlorotica grows faster when exposed to light than when placed in the dark
D) Elysia chlorotica grows in the dark when food sources are available.

Answer 1

Answer:

The correct answer is - B) Elysia Chlorotica grows when exposed to light in the absence of other food sources

Explanation:

If placing Elysia Chlorotica in presence of the food sources in the presence or absence of light it still grows as normal. However, if placing in the light in absence of the food sources it should not grow if it is not able to perform photosynthesis but it does which means there is a photosynthesis process also involve in the Elysia.

Photosynthesis is the process that involves the production of energy and nutrition in presence of light with water and atmospheric carbon dioxide.
