Answer:
Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.
Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
Answer:
I would say that A is the correct answer. Foods release amino acids. Hope this helps. :D
Blood vessels visible in the posterior view of the heart include the Superior and inferior vena cava and the pulmonary veins. The superior vena cava and the inferior vena cava drain systemic venous blood into the posterior wall of the right atrium. The pulmonary veins transport blood from the lungs back to the heart and are best seen in posterior view of the heart. Other features visible in the posterior view include, right and left atrium, right and left ventricle, aorta, aortic arch, pulmonary veins and arteries, coronary sinus, coronary artery and posterior interventricular artery.
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
Answer:
Feed back inhibition of glycolysis
Explanation:
Cell needs to regulate their metabolic pathways and reaction so that resources they have do not get waste and only than much product is formed which is required to be used.
Cellular respiration is most commonly regulated by the feedback inhibition of glycolysis. The most important regulatory step in the feedback inhibition of glycolysis is the phosphofructokinase reaction. This reaction is inhibited by ATP. ATP lower the affinity of enzyme for fructose-6- phosphate and inhibit the reaction thereby regulate cellular respiration.
