Answer:
Iodine
Explanation:
Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.
If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.

Answer:
The answer is D
Explanation:
Since the structure uses light energy, we can only assume that it's a chloroplast, since only chloroplasts contain chlorophyll and can absorb light energy.
Chloroplasts use carbon dioxide and water to make glucose, with oxygen as a byproduct.
The glucose produced is then used in metabolic reactions in the organism.
