In a simple food chain: Grass $\rightarrow$ Grasshopper $\rightarrow$ Frog $\rightarrow$ Snake. If the green grass traps $1000\text{ units}$ of solar energy, and only $10\%$ of energy passes to each next level, how much energy reaches the frog?
  1. $100\text{ units}$
  2. $10\text{ units}$
  3. $1\text{ unit}$
  4. $0.1\text{ units}$

Solution

Grass has $1000\text{ units}$. Grasshopper receives $10\%$ of $1000 = 100\text{ units}$. Frog receives $10\%$ of $100 = 10\text{ units}$.
