In an energy pyramid, the amount of energy at the producer level is 475,650 kilocalories. the pyramid has four trophic levels, including the producer level. assuming that 10% of the energy is retained at every level, how much energy is available for the second-level consumers?

There are three energy level in the energy pyramid. The producers have the 100% energy and the primary consumers feed on the producers and obtain 10% energy the producers have and secondary consumers feed on the primary consumers.

The energy left at this level is 10% of the energy that primary consumers have.

Hence, Producers will have 475,650 kilocalories

Primary consumers will have 475,65 kilocalories

Secondary consumers will have 4756.5 kilocalories

4756.5 kilocalories

Explanation:

i already took the test

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.

substitution is the answer in this case
