The food you eat. It contains calories, right? Calories are simply units of energy.
I will try to simplify so as not to go into a lengthy biochemistry lesson. Essentially, carbohydrates and lipids are broken down during the metabolic pathways to produce ATP via such processes as anaerobic and aerobic glycolysis, the citric acid cycle (krebs cycle), & the electron transport chain.
Think of those processes as a Willy Wonka factory machine. You drop in a glucose molecule (what lipids and carbohydrates are essentially broken down to before they hit the first steps in ATP production) and at the end of the mechanical "assembly line," you will have ATP molecules.

The energy for chemosynthesis comes from chemical reactions, instead of sunlight like in photosynthesis. Specifically, chemosynthetic organisms use energy released from chemical compounds like hydrogen sulfide, methane, or iron to convert carbon dioxide into organic molecules. This process is common in environments where sunlight cannot reach, such as deep-sea hydrothermal vents.

∙ 14y agoThe energy in photosynthesis reactions comes from sunlight. Sunlight must provide the activation energy to start the process of photosynthesis. For this reason, plants cannot grow well in the dark (and those that do don't rely on photosynthesis for energy).

chemosynthesis takes chemicals from the environment and uses it to synthesise energy
Plants, algae, and some bacteria obtain their energy from photosynthesis, while certain bacteria and archaea species obtain their energy from chemosynthesis. Photosynthesis converts sunlight into energy, while chemosynthesis uses inorganic compounds as a source of energy.
Chemosynthesis and photosynthesis both involve converting energy into organic molecules. However, chemosynthesis uses inorganic compounds as a source of energy, while photosynthesis uses light. Both processes are vital for sustaining life in certain ecosystems.
they use hydrotheral vents(thermal energy or heat energy)
how are they diffrent

chemosynthesis takes chemicals from the environment and uses it to synthesise energy
chemical compounds such as sulfides that come from cracks in the ocean floor.

Plants, algae, and some bacteria obtain their energy from photosynthesis, while certain bacteria and archaea species obtain their energy from chemosynthesis. Photosynthesis converts sunlight into energy, while chemosynthesis uses inorganic compounds as a source of energy.
The source of energy for chemosynthesis is typically inorganic compounds such as hydrogen sulfide, methane, or ammonia. Chemosynthetic organisms use this energy to convert carbon dioxide into organic molecules, without relying on sunlight like photosynthesis.
Chemosynthesis is the process by which organisms use chemical energy to produce food. This is different from photosynthesis, which is the process by which green plants and some other organisms use sunlight to convert carbon dioxide and water into glucose for energy. Chemosynthesis does not require sunlight and can occur in environments where light is not available, such as deep-sea hydrothermal vents.

The reactants of photosynthesis are carbon dioxide and water, while the reactants of chemosynthesis are usually sulfur compounds or methane. Both processes involve the production of energy-rich molecules for the organism to use as a source of energy, but they occur in different types of organisms and utilize different energy sources.
The source of energy used in chemosynthesis is typically chemical compounds such as hydrogen sulfide, methane, or ammonia. These compounds are oxidized by bacteria or other organisms to produce energy for metabolism, in a process similar to photosynthesis but using inorganic sources rather than sunlight.
