Suppose a fox in a food web feeds only on rabbits, squirrels, mice and birds, all of which feed exclusively on plant material. A

Illusion [34]

Answer:

square metres of plant materials required to support the fox = 3650 m²

Explanation:

From the given information:

the daily caloric requirement of the fox = 800

In a year, we have = 800 kcal × 365 /year = 292,000 kcal/year

Also, only 10% of the energy at a particular trophic level can be passed onto the next.

the net productivity of the plant material = 8000 kcal/m²/yr

So, using 10% of energy at a particular level, the fox only need 80 kcal/m²/yr

The objective is to determine in square meters, how many materials are required to support the fox.

square metres of plant materials required to support the fox = $\dfrac{292,000}{80}$

= 3650 m²

A 100 square mile area of national forest is how many acres ? how many hectares?

KengaRu [80]

Based on the calculations, the area of national forest is equal to 64,000 acres and 25,600 hectares respectively.

<h3>How to calculate the area of a square?</h3>

Mathematically, the area of a square can be calculated by using this formula;

A = x²

<u>Where:</u>

A is the area of a square.

x is the side length of a square.

<h3>What is measurement?</h3>

Measurement refers to a process through which the dimensions, size (weight), or other physical quantities of magnitude that are associated with an object or land is taken, especially for use in a scientific research and experiment such as direct comparison.

<h3>How to convert the units?</h3>

1 square mile = 640 acres

100 square mile = X acres

Cross-multiplying, we have:

X acres = 640 × 100

X acres = 64,000 acres.

For the area in hectares, we have:

1 hectare = 2.5 acres

X hectare = 64,000 acres

Cross-multiplying, we have:

2.5X acres = 64,000 acres

X = 64,000/2.5

X = 25,600 hectares.
