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 = 
= 3650 m²
Thank you for the answer:)
2W+2L=66
W=1/2L
2(1/2L)+2L=66
Simplifies to L+2L=66
Simplifies to 3L=66
Or L=22.
If W=1/2L, then W =1/2(22).
W=11.
To check our work, 2W+2L=66.
2(11)+2(22)=66.
22+44=66
66=66 Check.
<span>Denmark is a goo example of a nation-state because nearly all Danes speak Danish and live in Denmark. So in this case the correct answer would be C. Nearly the entire population are ethnic Danes who speak Danish.</span>
