Question

Consider the pyramid of energy of an ecosystem given below:

If \(T_4\) is equivalent to 1000 J, what is the value at \(T_1\)

• A. \(\frac{10000}{10}J\)
• B. \(\frac{10000}{10}\times 4\ J\)
• C. 10,000 J
• D. 10,00,000 J

Answer 1

The Correct Option is D

The pyramid of energy represents the flow of energy through different trophic levels in an ecosystem. There is approximately a 10% energy transfer efficiency from one trophic level to the next. This means that each level above retains about 10% of the energy from the level below it.
In this pyramid, T$_4$ represents the top trophic level, and T$_1$ represents the producers (the base of the pyramid). If T$_4$ has 1000 J, then:
\(T_3 = 1000 J \times \frac{100}{10} = 10,000  J\)
\(T_2 = 10,000  J \times \frac{100}{10} = 100,000 J\)
\(T_1 = 100,000  J \times \frac{100}{10} = 10,00,000  J \)
