B) Storing excess calories as fat.
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
