Answer:
Answer 9 - 100 joules energy was at the producer level
Answer 10 - Remaining energy is used in metabolism
Explanation:
Answer 9
The energy at each trophic level is only 10% of the energy at its previous trophic level.
The energy at producer level is X
% of
Joules
Joules
Answer 10
Because the remaining 90% energy is utilized by the producer for its metabolism
Explanation:
The given data is as follows.
P = 3 atm
=
=
= 9 L =
(as 1 L = 0.001
),
= 15 L =
Heat energy = 800 J
As relation between work, pressure and change in volume is as follows.
W =
or, W =
Therefore, putting the given values into the above formula as follows.
W =
=
= 1823.85 Nm
or, = 1823.85 J
As internal energy of the gas is as follows.
= Q - W
= 800 J - 1823.85 J
= -1023.85 J
Thus, we can conclude that the internal energy change of the given gas is -1023.85 J.
