Question

1. a full - sized cow needs about 100 square feet of pasture to graze on each day. assume an average sized classroom is about 600 square feet. how many classrooms worth of pasture would be needed to keep a cow alive for a year?
2. which trophic level do you think is the most important for the ecosystem and why?

Explanation:

Step1: Calculate the total pasture needed for a year

Assume a year has 365 days. A cow needs 100 square feet per day. So the total pasture needed for a year is \(100\times365 = 36500\) square feet.

Step2: Calculate the number of classrooms

An average - sized classroom is 600 square feet. Let \(n\) be the number of classrooms. Then \(n=\frac{36500}{600}\approx60.83\)

Answer:

Approximately 61 classrooms.
