base on the ten percent rule, determing how many kilocalories of energy the teritaiary consumer tuna will receive.

Answer 1

The ten percent rule states that only about 10% of the energy from one trophic level is transferred to the next trophic level. Therefore, if the tertiary consumer (tuna) obtains energy from a secondary consumer, only about 10% of the energy from the secondary consumer will be transferred to the tuna.

So, to determine how many kilocalories of energy the tertiary consumer tuna will receive, you need to know the energy content of the secondary consumer it feeds on. Let's say the energy content of the secondary consumer is 1000 kilocalories.

Using the 10% rule, the amount of energy transferred to the tertiary consumer tuna will be:
10% of 1000 kilocalories = 0.1 * 1000 = 100 kilocalories.

Therefore, the tertiary consumer tuna will receive approximately 100 kilocalories of energy.
