ENERGY
Fats supply a number of nutrients to the body. They are the main source of fatty acids and are also synthesized to provide energy to the cell.
Minerals do not supply plants with energy. The only source of energy for a plant is sunlight.
Algae use photosynthesis to generate their own sugars [food] using sunlight as energy. Water and Carbon dioxide [CO2] are the raw ingredients and are found in plenty supply. So for the most part it does not "eat". It does absorb water, trace nutrients, and minerals through it's membrane [skin] via osmosis, but that is not it's energy source.
It is required to supply chemical energy, organic molecules, and essential nutrients
Nutrition is the proper supply of nutrients for the proper growth and development and maintenance of the human body.
yes
Fats Carbohydrates (sugars) Proteins
Coal
Yes it is true.
Carbohydrates supply glucose as the main source of energy for the body.
Biomass gets its energy from the sun. All organic matter contains stored energy from the sun. During a process called photosynthesis, sunlight gives plants the energy they need to convert water, carbon dioxide, and minerals into oxygen and sugars. The sugars, called carbohydrates, supply plants (or the animals that eat plants) with energy. Foods rich in carbohydrates (like spaghetti) are a good source of energy for the human body!
