Question

write differences between a) autographic nutrition-heterotrophic nutrition b) Ingestion-digestion c) Light reaction- dark reaction d) chlorophyll -Chloroplast look​

Answer 1

Solution :

a) “Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition.”

b) The main difference between ingestion and digestion is that ingestion is the taking of food into the body whereas digestion is the breakdown of food into small molecules that can be absorbed by the body. Ingestion can be taking food either into the mouth in animals or into the cytoplasm in protozoans.

c) The light reaction is the initial stage of photosynthesis which traps light energy to produce ATP and NADPH, whereas dark reaction is the second step of photosynthesis which utilizes the energy from ATP and NADPH to produce glucose.
