Answer:
c. mitochondrion, virus, hemoglobin, glucose, water molecule
Explanation:
The mitochondrion is a membrane which is found in cytoplasm of eukaryotic cells. It is also known as power house of cells. This is largest from virus, hemoglobin, water molecule and glucose.
Virus is second largest and is small infectious agent. It has capability to infect many organisms and living cells. Hemoglobin is protein which is present in red blood cells. Glucose is a type of sugar presence in the blood. Water molecule is composed of hydrogen and oxygen and is smallest among the others.
Oxygen is an abiotic factor that is beneficial by-product of primary production.
<u>Explanation:</u>
The non living parts of an ecosystem that mainly affects the living organisms in it are called as an abiotic factor. These can include soil, temperature, water, oxygen and sunlight. The major energy source in earth is Oxygen which is abiotic factor.
It is very essential for the photosynthesis process to take place. Here, the plants converts water and carbon dioxide into oxygen and sugar. This becomes food for plants. Then these plants are eaten by animals. Thus oxygen is an important and beneficial by-product of photosynthesis. Oxygen is also very important for the survival of human beings.
