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.

Aarush , there will be not enough plants to feed so many water insects . So, at a particular time all plants will finish . So , there will be nothing left for the water insects so they will also die !

Ans 9:

Class : Class 8
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.

Class : Class 9
why

Ans 2:

Class : Class 4
Figure A can be folded horizontally, figure B can be folded diagonally, figure D can be folded vertically to get their mirror images whereas figure C is asymmetric, so the odd one out is figure C

Answer is asymmetrical figure, because all the other figures are symmetrical.

Ans 10:

Class : Class 3
nonsense question

Ans 11:

Class : Class 9
The images given in Options A, B and D are symmetrical images. That means all three have at least one line of symmetry. Line of symmetry is any line drawn through the image which divides the image into two exactly equal parts, and these parts are mirror images of each other. A.The part above the red line (line of symmetry) and the 7part below the red line are mirror images of each other.7410`1 B.The parts on both sides of the red line (line of symmetry) are mirror images of each other. C.There can be no line of symmetry that can divide this image into two equal parts which are mirror images of each other. D.The part on the left side of the red line (line of symmetry) and the part on the right side of the red line are mirror images of each other. Hence, Option C is the odd one out.
