i believe the correct answer is c but i’m sorry if i’m not correct
Answer:
Explanation:
I do not have access to your diagram but based on what I know, a food web cannot sustain itself without decomposers. They are the main guys who break down dead animals, plants into organic or inorganic nutrients which are needed by the primary producers to grow. So if decomposers are not there then producers cannot produce and thus herbivores cannot live and carnovers die out as well. Hope this makes sense.

The pressure at the point on the roof where the speed is 60mph is 14.66 psi
<u>Explanation:</u>
The question follows Bernoulli's equation
P1 + 1/2 ρ V1² = P2 + 1/2 ρ V2²
V1 = 40 X 5280 / 3600 = 58.7 ft/s
V2 = 60 X 5280 / 3600 = 88 ft/s
P2 = P1 + 1/2 ( 0.00238 ) [(58.7)² - (88)²]
P2 - P1 = -5.12lb/ft²
The negative pressure created tends to lift the roof.
We know,
P1 = 14.7 psi = 2116.8 lb/ft²
P2 = 2116.8 - 5.12 lb/ft²
P2 = 2111.68 lb/ft²
P2 = 14.66 psi
Therefore, the pressure at the point on the roof where the speed is 60mph is 14.66 psi
