A scientist claims that Elysia chlorotica, a species of sea slug, is capable of photosynthesis. Which of the following observations provides the best evidence to support the claim?1) Elysia chlorotica grows in the dark when food sources are available.2) Elysia chlorotica grows faster when exposed to light than when placed in the dark.3) Elysia chlorotica will die if not exposed to light.4) Elysia chlorotica grows when exposed to light in the absence of other food sources.

Respuesta :

The observation which best supports the claim that Elysia chlorotica is capable of photosynthesis is number 4. The ability to photosynthesize doesn't mean it won't be able to eat other food sources when abailable, but that it will be able to survive and grow in abscense of food sources if it is exposed to light, as light is necessary to obtain the energy for the process of photosyntesis.
