Question

Используя правило экологической пирамиды (правило Линдемана), определите, на сколько увеличилась масса волка, если в течение дня он поймал и съел зайца-беляка массой 5,3 кг. Учтите, что массовая доля воды в организме зайца составляет 69% от общей массы животного. Ответ должен быть предоставлен в граммах.

Answer 1

Ответ:

на 1000 грамм гдето примерно

Answer 2

Ecological Pyramid and Lindeman's Rule

The ecological pyramid is a graphical representation of the trophic levels in an ecosystem, showing the flow of energy and biomass between different organisms. Lindeman's Rule, also known as the 10% rule, states that only about 10% of the energy from one trophic level is transferred to the next trophic level. This rule can also be applied to the transfer of biomass between trophic levels.

Calculation of Wolf's Mass Increase

To determine the increase in the mass of the wolf after consuming a 5.3 kg snowshoe hare, we need to consider the biomass transfer between the two organisms.

Given that the snowshoe hare has a water content of 69% of its total mass, we can calculate the dry mass of the hare by subtracting the water content from its total mass:

Dry mass of the hare = Total mass of the hare - (Water content of the hare * Total mass of the hare) Dry mass of the hare = 5.3 kg - (0.69 * 5.3 kg)

Let's calculate the dry mass of the hare:

Dry mass of the hare = 5.3 kg - (0.69 * 5.3 kg) Dry mass of the hare = 5.3 kg - 3.657 kg Dry mass of the hare = 1.643 kg

According to Lindeman's Rule, only about 10% of the biomass from one trophic level is transferred to the next trophic level. Therefore, the wolf will gain 10% of the dry mass of the hare as its own biomass.

Increase in the mass of the wolf = 10% of the dry mass of the hare Increase in the mass of the wolf = 0.1 * 1.643 kg

Let's calculate the increase in the mass of the wolf:

Increase in the mass of the wolf = 0.1 * 1.643 kg Increase in the mass of the wolf = 0.1643 kg

Therefore, the mass of the wolf will increase by approximately 164.3 grams after consuming a 5.3 kg snowshoe hare.

Note: The calculations provided above are based on the assumption that Lindeman's Rule applies and that the wolf consumes the entire mass of the hare. In reality, there may be variations and complexities in the transfer of biomass in an ecosystem.
