Question

Рассчитайте, пользуясь правилом 10%, долю энергии, поступающей на 4 уровень, при условии, что её общее кол-во на первом уровне 1000 единиц.

Answer 1

Ответ:

1 единица

Объяснение:

По правилу 10% на каждый следущий уровень переходит только 10% энергии, то есть:

1 уровень - 1000 (по условию)

2 уровень - 1000 × 10 / 100 = 100

3 уровень - 100 × 10 / 100 = 10

4 уровень - 10 × 10 / 100 = 1

Answer 2

Calculation of Energy Share on the 4th Level

To calculate the share of energy that reaches the 4th level using the 10% rule, we need to apply the rule recursively. The 10% rule states that only 10% of the energy from one trophic level is transferred to the next level.

Given that the total energy at the first level is 1000 units, we can calculate the energy share on the 4th level as follows:

1. First level: 1000 units 2. Second level: 10% of the first level = 100 units 3. Third level: 10% of the second level = 10 units 4. Fourth level: 10% of the third level = 1 unit

Therefore, the share of energy that reaches the 4th level is 1 unit.

Please note that this calculation is based on the assumption that the 10% rule applies consistently across trophic levels. However, it's important to keep in mind that energy transfer in ecosystems can be complex and may vary depending on various factors.
