About 90% of the energy is lost to heat moving up one trophic level. Only 10% actually makes it to the next organism. Assuming the chain goes produce, primary consumer, secondary consumer, humans receive about 1% of the original energy from the cow’s food.
Answer:
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
Explanation:
There are four major biological molecules called biomolecules in nature namely; carbohydrates, proteins, nucleic acids and lipids. These four molecules form the bedrock upon which life is built. The biomolecules mentioned above are POLYMERS formed as a result of the combination of two or more simpler molecules called MONOMERS in a process called CONDENSATION.
The monomer of each polymeric biomolecule is as follows;
Carbohydrates - monosaccharides
Proteins - amino acids
Nucleic acids - nucleotides
Lipids - fatty acids (hydrocarbon chains)
say you eat mcdonalds everyday and all that grease and artifical flavorings that weakens ur umune system but if u eat ur fruits,veggies, protiens,and exc ur ummune system is stronger than those who eat mcdonalds all day
The right answer is D
The stomata are at the level of the epidermis of the leaves and aerial stems, the place of passage of the gases (carbon dioxide, oxygen, water vapor) which play a fundamental role in the physiology of the plant. These structures (which can be considered as "mini-organs") interactively regulate these exchanges. They are the terrestrial plants that constitute the true interface between the external atmosphere and the internal gas network.
