Answer:

A By returning nutrients to the soil

Explanation:

Here are the options

A By returning nutrients to the soil

B By releasing oxygen into the air

C By making space for new animals

D By decreasing the population of herbivores

The process by which mushrooms act on dead trees provide nutrients that are necessary for the process of photosynthesis.

Types of decomposers

  1. Fungi - mushroom is an example of a fungi
  2. Bacteria
  3. Insects - beetle is an example of an insect
  4. Earthworms

Functions of a decomposer

  1. A decomposer recycles dead plants and animals to release nutrients into the soil.
  2. They are ecological cleaners. they carry out this function by disintegrating dead plants and animal remains.

<h3><u>Answer</u>;</h3>

Price floor

When the government sets a price for wheat that is above the equilibrium price, it is imposing a<u> price floor</u>.

<h3><u>Explanation</u>;</h3>
  • <u>Price floors prevent a price from falling below a certain level. When a price floor is set above the equilibrium price, quantity supplied will exceed quantity demanded, and excess supply. </u>
  • <u>Price control </u>occurs when the government laws regulate prices instead of letting market forces determine prices.
  • <u>Price ceilings</u> prevent a price from rising above a certain level.

Water having a density of 1000 kg/m^3 is flowing with a velocity of 3 m/s through a round pipe. There is a restriction within th
Fofino [41]

Answer:

12 m/s

Explanation:

Using the continuity equation, which is an extension of the conservation of mass law

ρ₁A₁v₁ = ρ₂A₂v₂

where 1 and 2 indicate the conditions at two different points of flow, in this case, point 1 is any normal position in the pip and point 2 is the conditions at the restriction.

ρ = density of the fluid flowing; note that the density of the fluid flowing (water) is constant all through the fluid's flow

A₁ = Cross sectional Area of the pipe at point 1 = (πD₁²/4)

A₂ = Cross sectional Area of the pipe at the restriction = (πD₂²/4)

v₁ = velocity of the fluid flowing at point 1 = 3 m/s

v₂ = velocity of the fluid flowing at The restriction = ?

ρ₁A₁v₁ = ρ₂A₂v₂

Becomes

A₁v₁ = A₂v₂ (since ρ₁ = ρ₂)

(πD₁²/4) × 3 = (πD₂²/4) × v₂

3D₁² = D₂² × v₂

But

D₂ = (D₁/2)

And D₂² = (D₁²/4)

3D₁² = D₂² × v₂

3D₁² = (D₁²/4) × v₂

(D₁²/4) × v₂ = 3D₁²

v₂ = 4×3 = 12 m/s
