Answer:
Autotrophs, but not heterotrophs, can nourish themselves beginning with and other nutrients that are inorganic.
Explanation:
Unlike heterotrophs, autotrophs such as green plants, are able to synthesize their food (in form of sugar molecules) starting with inorganic molecules like atmospheric carbon dioxide, water in the presence of sunlight.
This is commonly known as photosynthesis. The equation is shown below
6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy
Answer:
oxygen gas
red blood cells
platelets
Explanation:
» <u>Concepts</u>
Your blood is composed of four main things: <u>red blood cells</u> (that transport <u>oxygen</u>), <u>white blood cells</u>, <u>platelets</u>, and <u>plasma</u>. Red blood cells transports oxygen and takes out CO2, white blood cells fight bacteria and viruses, and platelets clot together to stop bleeding.
<u>Bile</u> is a fluid that is produced by the liver and stored in the gallbladder, so it's not a main component of blood.
The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere. There are a few exceptions to this, such as ecosystems living around hydrothermal vents on the ocean floor, which derive their energy from the chemical compounds such as methane and hydrogen sulfide. In either case, the overall productivity of an ecosystem is controlled by the total energy available.
