A diagrammatic representation of different trophic levels in an ecosystem is given below Give example of the organism for each trophic level either from aquatic or terrestrial ecosystem.

Some pictures (a) to ( c) are given below. Tell which of them show: 3xx3/4 = 2 1/4

Find the value of x for which the sixth term of : (sqrt(2^(log(10-3^x)))+ root (5)(2^((x-2)log 3)))^n is equal to 21, if it is known that the binomial coefficient of the 2nd, 3rd and 4th term in the expansion represent respectively the 1st, 3rd and 5th term of an A.P. (the symbol log stands for logarithm to the base 10).

A game of chance consists of spining an arrow which comes to rest pointing at one of the numbers 1,2,3,4,5,6,7,8, and these are equally likely outocomes. What is the probability that it will point at (i) 8 ? (ii) an odd number ? (iii) a number greater than 2 ? (iv) a number less than 9 ?

Given below are some functions of xand t to represent the displacement (transverse or longitudinal) of an elastic wave. State which of these represent (i) a travelling wave, (ii) a stationary wave or (iii) none at all: y = 3 sin (5x-0.5t)+4cos(5x-0.5t)
