Question

how much energy is available at the third trophic level of the first trophic level has 300 000 kilometers of available energy and the loss rate between trophic levels is 90%?

Answer 1

The energy available at the third trophic level can be calculated by multiplying the energy available at the previous trophic level by the trophic level transfer efficiency, which is the production at present trophic level divided by the production at previous trophic level. In this case, the energy at the third trophic level would be 0.9 multiplied by the energy available at the second trophic level.

Step-by-step explanation:

The energy available at the third trophic level can be calculated by multiplying the energy available at the previous trophic level by the trophic level transfer efficiency (TLTE) - which is the production at present trophic level divided by the production at previous trophic level. In this case, the TLTE is 90% (or 0.9) because the loss rate between trophic levels is 90%. Therefore, the energy at the third trophic level would be 0.9 multiplied by the energy available at the second trophic level, which is 0.9 x 300,000 kilometers. This equals 270,000 kilometers of available energy at the third trophic level.
