In an energy pyramid, the amount of energy at the producer level is 475,650 kilocalories. the pyramid has four trophic levels, i
AURORKA [14]

The energy available for the second-level consumers is <u>4756.5 </u>kilocalories.

A trophic level is a  position in the food chain or nutrient cycle of an ecosystem. Based on their eating habits, organisms in a food chain are divided into various levels. The first trophic level is usually occupied by producers that can synthesize their own food.

The efficient energy transfer from one trophic to another is only 10% rest of the energy is lost in the ecosystem. The studies of the transfer of energy in different food chains in a large number of ecosystems have revealed a uniform pattern, which is stated as the 10 percent law by Lindemann. According to this law, only 10 percent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.

Calculation:

Producers (475650 kilocalories) —>  Primary consumers (10% of 475650 = 47565 kilocalories) —> Secondary consumers (10% of 47565 = 4756.5 kilocalories).

So, the energy available for second-level consumers is 4756.5 kilocalories.

there will be less salt inside the cells so all the water will enter the cells. if there is also salt present outside of the cell then the water and the electrolites(salt) will equalize between the inside and the outside of the cell.
