Answer:
1. 36500 kcals
2. Producers
Step-by-step explanation:
As organisms in one trophic level feeds on another organism in another trophic level, one must bear in mind that only 10% of available energy at each trophic level is transferred.
According to this question, the secondary consumer trophic level has 365 kcals of energy. Since there are primary consumer and producer trophic levels before this, it means that 100 times of energy was previously available at the producer level. Hence, 365 kcal × 100 = 36500 kcal of energy is available at producer level.
2. The producer level has the most available energy (kcal) among the trophic levels because they get it directly from the sun and are the first participants of the energy transfer.
