Plants employ photosynthesis to convert water, sunshine, and CO2 into oxygen and simple sugars that the plant may use as fuel. It is it important to add fertilizer to some soils because fundamental producers serve as the foundation of an ecosystem, fueling the subsequent trophic levels.
<h3>What is the photosynthesis process?</h3>
In the photosynthesis process, plants absorb carbon dioxide (CO2) and water (H2O) from the air and soil during photosynthesis. Water is oxidative within the plant cell, which means it loses electrons, but carbon dioxide is reductive, which means it receives electrons.
This converts water to oxygen and nitrogen to glucose. Photosynthesis is often used by plants to transform water, sunlight, and CO2 into oxygen and simple carbohydrates that the plant may utilize as fuel.
Therefore, Some soils require nutrients because basic producers contribute as the base of an ecosystem, feeding succeeding trophic levels.

Answer:
a) 3X + 2Y = 36
b) X = 6 , Y = 9
c) 27
Explanation:
Individual consumes : X and Y
Spends : $36 per time period
unit cost : $3 per unit for X
$2 per unit for Y
utility function : U( X, Y ) = .5XY
<u>A) Budget equation mathematically</u>
X* Px + Y* Py = M
3X + 2Y = 36
Px and Py = unit cost for X and Y
M = Total spent ( revenue )
<u>b) Values of X and Y that will maximize utility </u>
Maximum utility ( MRS ) = Px / Py ,
MRS = MUx / MUy
= Y/X = 3/2
∴ 2Y = 3X
From BC : 6X = 36 ( X = 6 plug into mathematically equation above )
∴ X = 6 , hence Y = 9
<u>c) Total utility generated per unit of time </u>
U( X,Y ) = .5XY
= 0.5 * 6 * 9 = 27
A sociologist might say that this is an example of how economic action is <u>embedded in</u> social relationships.

The effective rate on these bonds is 7.17%
<h3>What is the effective rate?</h3>
The effective interest rate of a bond is the rate that equates the present value of the bond's future interest payments and the bond's maturity value to the bond's current market value.
The effective interest rate can be determined using a financial calculator:
- Cash flow in year 0 = -490,222
- Cash flow from period 1 - 12 = 6% x 540,000 = 32,400
- Cash flow in year 6 or period 12 = $540,000
effective interest rate = 7.17%
