Normally, the number of organisms in a food pyramid decreases as the trophic level increases. But in some cases, the pyramid may be inverted, for instance, when the productor is a single tree, and beetles eats its leaves, and birds eat the beetles. There is the biomass pyramid too, that represents the amount of mass present in the organisms of the food chain.
Answer:
The second answer is correct
Answer:
The main purpose of light dependent reactions of photosynthesis is to generate ATP and NADPH.
Explanation:
Photosynthesis consist of two reactions 1 light reaction 2 dark reaction .The light reaction occur in the thylaKoid of Grana to produce Adenosine tri phosphate (ATP) and NADPH
Role of ATP
ATP is an energy rich molecule which undergo hydrolysis to provide energy for Carbon di oxide fixation during dark reaction. The carbon di oxide fixation is very much important to produce glucose.
Role of NADPH
NADPH act as reducing equivalent that carry out the reduction of phosphoglyceric acid formed in the first step of light independent reaction to generate phosphoglyceraldehyde(PGALD). Some PGALD then undergo various enzymatic reaction to form glucose and rest are utilized to regenerate ribulose bis phosphate(RUBP).
The lateral wall of the nasal cavity is formed partly by the maxilla, partly by the ethmoid bone, and partly by the perpendicular part of the palatine bone. Further back, where the nasal cavity becomes the nasopharynx, the lateral wall is formed by the medial pterygoid plate.
