Moving up trophic levels there is an increase in energy, entropy, and biomass.
a. true
b. false

The given statement is false.

Explanation:

There is loss of energy taking place when one moves up in the trophic level because of the activities like respiration and movement. It is known that approximately 90 percent of the energy is lost in between each of the trophic level. The concentration of energy level at each of the trophic level diminishes as one moves through an ecosystem, about 10 percent of the energy at any of the trophic level is conducted towards the next level, and the remaining of the energy is lost due to certain metabolic procedures.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

it would be a gas formation
