8 0

Answer:

This is due to lactic acid accumulation in Emma's leg muscles.

Explanation:

In the absence of oxygen in the muscle cells, the cell switches from performing aerobic respiration to lactic acid fermentation. The lactic acid fermentation produces lactic acid as a product, which builds up in the muscle cells of the body causing a burning sensation and pain. This often happens during exercises.

This is the cause of Emma's pain in her lower leg muscles. Lactic acid has been formed and accumulated in the muscle cells of her leg during the exercise with her brother.

The organism to have maximum energy would be the algae since ii will be at the lowest level. so the answer is 'B'.

Explanation:

The pyramid of energy shows the flow of energy from one trophic level to other. The lowest trophic level is occupied by the producers. In this case algae acts as the producer. Krill acts as the primary consumer, followed by leopard seal as the secondary consumer and finally killer whale as the tertiary consumer. The <em>lowest trophic level </em> contains maximum energy.

As we go upwards, only 10% of the energy gets transferred to the next trophic level.
