In the given food chain, tadpole feeds on water insect and in turn is eaten by small fish. If population of tadpole will decline with time then small fish population will also decrease as former is the food of later. On the other hand, water insect population will be positively affected because in the absence of predator prey population reproduces and flourishes.

The correct answer is C because if organism X wipes out all tadpoles in the community, then water insects' population grows with nothing to eat them. The small fish die because they have nothing to eat, and soon the big fish die too.

GIVE SOLUTION

Ans 3:

Class : Class 7
D is wrong.

Ans 4:

Class : Class 7
The answer will be D because big rubber band so more sound as the wide rubber band is striking back on more part of the wooden piece.

Ans 5:

Class : Class 4
Ans A would be right if it says Sharpest sound !Ans D is correct in this case as it ask loudest sound

Ans 6: (Master Answer)

Class : Class 1

Ans 7:

Class : Class 4
I have done some practical observations and found that the fatter rubber band produces louder sound than A,B,C .Correct ans... is D

Ans 8:

Class : Class 8
D D D IT IS D I WILL TELL YOU IT IS DI WILL TELL YOU THAT I AGREEWITH SOMEONE OVER HERE CALLED AYUSHI

Ans 9:

Class : Class 7
The answer should be d because the rubber band is wider so it is striking back on the wooden piece on more area.

Ans 10:

Class : Class 4
AS THINNER RUBBER WOULD BE PULLED TO A MAXIMUM DISTANCE HENCE MORE SOUND.

Ans 11:

Class : Class 7
@Soumya Bajaj is right. @Vansh Garg, have you measured the sound's frequency in Decibels? The correct answer is A because the thinner the rubber band, the more it will strech and the more it will strech, the more sound it will produce.(Master Answer)
