Scientist claims that Elysia chlorotica, a species of Sea slug, is capable of photosynthesis. which of the following observation
s provides the best evidence to support the claim? 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.
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.
Having someone to talk with about your thoughts and issues can help you feel better. Emotional support from someone who cares also helps. This is usually what therapy is for...
C. producer, the corn creates its own 'food' with photosynthesis. It's easier to remember as a flow chart producer(typically plants)->primary consumer(mostly herbivores)->secondary consumer(predators and other meat eaters) and decomposers(usually fungus) eat basically everything.
