Answers
Explanation:
Rhizopus stolonifer is dependent on sugar and starch, which it acquires from food matter, such as breads and soft fruits. The food source that is used by this mold is utilized for growth, nutrition, and reproduction. The spores that are produced through reproduction are commonly found in the air.

5.Differentiate Between:-
a)Saprophyte and Parasite
➡️Parasite is an organism that lives on or in another organism (called host), using it as a source of food and a place of temporary or permanent residence. Saprophyte is an organism that feeds on a decomposing matter from dead organisms. ... Saprophytes feed with decaying organic matter from dead organisms.
b)Aerobic and anaerobic respiration with regard
➡️Aerobic and anaerobic respiration with regardto products
The high amount of energy is produced and 38 ATP released at a time in aerobic respiration; Less amount of energy is produced and 2 ATP are released at a time in anaerobic respiration. and ethanol (plant cell) is the final product in anaerobic respiration. glucose to produce energ
c)Decay and putrefaction.
➡️Decay is the complete breakdown of organic matter by bacteria without giving out a foul smell. ... Putrefaction is the incomplete breakdown of organic matter,emitting a foul smell.
