Answer:
I believe your answer would be...
The number of animals greatly exceeded the carrying capacity, destroying the food sources and causing the population to decline.
Explanation:
Using the process of elimination its the only one that makes sense.
Answer:
a) D = 33.44 Lbmol/h
⇒ B = 62.56 Lbmol/h
b) D = 16.848 Kmol/h
⇒ B = 28.152 Kmol/h
Explanation:
global balance:
- F = D + B........................(1)
∴ F = 100 Lbmol/h
balance per component:
A: 0.4*F = 0.9*D + 0.1*B = 0.4*100 = 40 Lbmol/h..............(2)
B: 0.6*F = 0.1*D + 0.9*B = 0.6*100 = 60 Lbmol/h..............(3)
from (2):
⇒ 0.9*D = 40 - 0.1*B
⇒ D = ( 40 - 0.1*B ) / 0.9............(4)
(4) in (3):
⇒ 0.1*((40-0.1*B)/0.9) + 0.9*B = 60
⇒ B = 62.56 Lbmol/h............(5)
(5) in (1):
⇒ D = 100 - B
⇒ D = 37.44 Lbmol/h
∴ Lbmol = 0.45 Kmol
⇒ B = 62.56 Lbmol/h * ( 0.45 Kmol/ Lbmol ) = 28.152 Kmol/h
⇒ D = 37.44 Lbmol/h * ( 0.45 Kmol/h ) = 16.848 Kmol/h
The options to the question above are:
A-the population of cladophora will decrease, resulting in an increase in the trout population
B-there will be a larger decrease in the trout population, resulting in an increase in damselfy nymphs
C- increased stream volume will provide more area for the trout to reproduce, causing a large increase in the population of algae
D- the population of trout will decrease because the population of damselfly nymphs will decline
The most likely immediate effect of an increase in runoff containing cadmium on the trophic structure of the river community is that there will be a larger decrease in the trout population, resulting in an increase in damselfy nymphs
- Cadmium is known to increase in the food chain and also pile up in humans. It is often taken up in water by algae, insects, and then up the food chain to fish, where it is piled up it in their gills, liver and kidneys .
It is a very toxic heavy metal that comes into the environment through anthropogenic sources such as poor quality of surface water, marine water.
Conclusively we can therefore say that Option b is the right answer because trout is negatively affected by but not the case with damselfly.

I think the answer is tenfold
hope this helps :)
Answer:
If temperature is held constant, the equation is reduced to Boyle's law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase. ... Gay-Lussac's law states that at constant volume, the pressure and temperature of a gas are directly proportional.
