- Assuming that producers in an ecosystem have 1,000,000 kilocalories of energy, 100,000 Kilocalories of energy would be available to primary consumers.
- Producers is the trophic level with the greatest biomass
HOW IS ENERGY TRANSFERRED:
- In a food chain, energy is being transferred when one organism in a particular trophic level feeds on another organism in a lower trophic level.
- The lowest trophic level contains the producers, which are organisms that start the food chain. However, only about 10% of energy is available to the organism in the next trophic level as 90% is lost as heat.
Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.
WHAT IS BIOMASS:
- The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next.
- As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.
Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.
