if the flowers contain 30,000 kcal of energy, how much energy will the jackal obtain from eating the…

Explanation:

Step1: Recall energy - transfer rule

In a food - chain, only about 10% of the energy is transferred from one trophic level to the next.

Step2: Calculate energy at primary consumer level

The flowers are producers with 30,000 kcal of energy. The primary consumer gets 10% of this energy. So, energy at primary consumer level = $30000\times0.1 = 3000$ kcal.

Step3: Calculate energy at secondary consumer level

The secondary consumer gets 10% of the energy of the primary consumer. So, energy at secondary consumer level = $3000\times0.1=300$ kcal.

Step4: Calculate energy at tertiary consumer level

The tertiary consumer (road - runner) gets 10% of the energy of the secondary consumer. So, energy at tertiary consumer level = $300\times0.1 = 30$ kcal.

Step5: Calculate energy at quaternary consumer level

The quaternary consumer (jackal) gets 10% of the energy of the tertiary consumer. So, energy obtained by jackal = $30\times0.1=3$ kcal.
