Yeast is a fungus and needs a supply of energy for its living and growth. Sugar supplies this energy. (Your body also gets much of its energy from sugar and other carbohydrates.) Yeast can use oxygen to release the energy from sugar (like you can) in the process called "respiration". So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point - even yeast cannot grow in very strong sugar - such as honey).
so thats why i asked this question
could u send me the board papers if u have already written for 9th sa2
sorry i am in 10
and i dont have it
its ok
Yeast is a fungus and for it's growth it needs energy as our body needs, to the yeast it is supplied by the sugar. It uses the oxygen to release energy from the sugar. This process is known as respiration. hence, the more sugar is there, the more the yeast will flourish but up to a certain level. It will not flourish 9in very strong sugar like......Honey.

mark is as brainliest.............plzzz
