Ten percent of energy is transferred from one level to the next level on the energy pyramid. what happens to the other 90% of energy? a. it is stored as fat. b. it is given off as heat. c. it is stored as a protein. d. it is used in reproduction.

B. It is given off as heat.

Explanation:

Organisms feed on one another in an ecosystem in order to gain energy needed for their life processes. This feeding pattern is termed FOOD CHAIN. Each organism occupies a position in the food chain depending on the pattern of their feeding behavior. This level is called TROPHIC LEVEL. So, the food chain progresses when one organism in a particular trophic level feeds on another organism in a lower trophic level.

As organisms in each trophic level feeds on another, only about 10% of the energy is available to that organism. This is because majority of the energy (about 90%) has been lost as heat when organisms engage in their metabolic activities. For example, a producer which starts a food chain obtains energy by producing its own food via photosynthesis, it is fed on by a goat in the next trophic level. Only 10% of the total energy is available to the goat because 90% of the energy has been lost via heat when the plant undergoes metabolic activities.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

i think the answer is g1
