A low-mass star never gets hot enough in the core to fuse helium into carbon.
Chemoheterotrophs obtain carbon by consuming organic compounds from their environment. They cannot produce their own food through photosynthesis and depend on other organisms for a source of carbon. This carbon is used in their metabolism to generate energy and build cellular components.
Carbon dioxide is not used as a fuel because it is a product of combustion or respiration, not a source of energy. Cow dung, on the other hand, contains organic matter that can be converted into biogas through a process called anaerobic digestion, making it a renewable source of energy. While carbon dioxide can be captured and utilized in certain industrial processes such as carbon capture and storage, it is not a direct source of energy in the same way as cow dung.
Respiration is essential for living organisms as it is the process through which cells generate energy by converting glucose and oxygen into ATP, which is the energy currency of the cell. It also helps in releasing carbon dioxide, a waste product, from the body.
Algae uses carbon dioxide through the process of photosynthesis. In this process, algae absorb carbon dioxide from their surroundings and transform it into organic compounds using sunlight as an energy source. This helps algae to grow and generate oxygen as a byproduct.
In ecosystems, carbon refers to the element that cycles through living organisms and the environment, playing a key role in processes like photosynthesis and respiration. Energy, on the other hand, is the ability to do work and is transferred through trophic levels in an ecosystem via food chains. Both carbon and energy are essential for the functioning of ecosystems, but while carbon cycles, energy flows through ecosystems.
Mitochondria generate energy through the process of aerobic cellular respiration.
They get energy from sunlight.They get carbon themselves.

It has to generate energy. Energy is generated through respiration.
It is used to generate electricity, without the carbon dioxide emissions of non-renewable energy.
Respiration is the process by which organisms take in oxygen and release carbon dioxide to produce energy. In humans, it involves breathing in oxygen through the lungs and transporting it to cells via the bloodstream, where it is used in cellular respiration to generate energy. Carbon dioxide, a byproduct of this process, is then expelled from the body through exhalation.
When you breathe in oxygen, it is used by your body to generate energy through a process called cellular respiration. Oxygen is then converted into carbon dioxide, which is exhaled back into the atmosphere.
No. Like other animals, a cobra gets energy through aerobic respiration, whereby sugars obtained from food react with oxygen to produce water, carbon dioxide, and energy.
Chemical energy is stored in coal, as it is a fossil fuel composed mostly of carbon. This energy is released when coal is burned through combustion processes to generate heat and electricity.
Sperm cells do not have mitochondria and cannot generate energy through aerobic respiration. Therefore, they do not require oxygen or produce carbon dioxide. Instead, sperm cells rely on glycolysis to produce energy in the form of ATP.
Plants get their energy from sunlight and generate food through photosynthesis (using water, carbon dioxide and energy from the sun to generate carbohydrates). Whether or not they live in fresh water has nothing to do with this, though being immersed in water like seaweed is would effect access to light.
