Question

there are generally fewer animals at the top of the trophic pyramid than at the bottom. this pattern is related to the loss of energy from one trophic level to the next highest trophic level. approximately 10% of the energy at one trophic level is transferred to the next trophic level. assuming that 10% of the total energy at one level is transfered from one trophic level to the next, calculate the percentage of energy that tertiary consumers receive from producers. percentage energy. %

Explanation:

Step1: Identify trophic - level transfers

Producers are at the first trophic level, and tertiary consumers are at the fourth trophic level. There are 3 energy - transfer steps from producers to tertiary consumers.

Step2: Apply the energy - transfer percentage

Since 10% (or 0.1 in decimal form) of energy is transferred from one trophic level to the next, the energy received by tertiary consumers from producers is calculated by multiplying the transfer factor for each step. So the energy percentage is $0.1\times0.1\times0.1$.

Step3: Calculate the result

$0.1\times0.1\times0.1 = 0.001$. To convert this to a percentage, we multiply by 100: $0.001\times100 = 0.1\%$.

Answer:

$0.1$
