The correct answer is option B, that is, functional group.
A functional group refers to a part of a molecule, which is a classified/recognizable group of bound atoms. The functional group provides the molecule with its characteristics, in spite of what molecule comprises it, they are the centers of chemical reactivity. The functional groups in a molecule require to be determined when naming.

Answer:
<u><em>The correct option is ' Organelle A is mitochondrion, Organelle B is chloroplast, and Organelle C is vacuole.'</em></u>
Explanation:
Mitochondria are known as the powerhouse of a cell. It is the site where cellular respiration takes place. As a result of cellular respiration, ATP is produced which is the main energy source for cells to carry out their normal processes. Mitochondria is present both in the plant as well as the animal cells.
Chloroplast is the organelle which is responsible for photosynthesis in plants. Photosynthesis is a process by which plants make their own food by using light energy from the sun. Chloroplast is present in plant cell but absent in an animal cell.
The vacuole is present in both the plant and animal cells. In plant cells the vacuole is bigger and present in the centre of the cell and it gives the cell its shape.
Answer:
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are ultimately recycled in the ecosystem while the energy is ultimately lost from the ecosystem to the universe at large. Energy in any ecosystem ultimately comes from the Sun.
