Question

На основі правила екологічної піраміди визначте, скільки потрібно планктону, щоб у чорному морі виріс і зміг існувати дельфін масою 300кг.

Answer 1

Буде так...У нашому випадку на першому місці буде стояти продуцент(планктон),потім консумент 1-шого порядку(риба,яка буде їсти цей планктон..потім уже буде дельфін-консумент 2-гого порядку.(він буде їсти консумент 1-шого порядку.
Виходить,для того щоб виріс і зміг існувати дельфін масою 300 кг,потрібно помножити на 10...кожний попередній рівень від дельфіна...виходить так...
Дано:                             За правилом екологічної піраміди        
m(дельфіна)=300кг.  продуцент(планктон)30000кг-консумент(1)3000кг
Знайти:                         Дельфін(300кг);
m(планктона)-?          ВІдповідь:30000 кг.
         

Answer 2

Determining the Amount of Plankton Needed for a 300kg Dolphin in the Black Sea

The ecological pyramid is a graphical representation designed to show the biomass or bio-productivity at each trophic level in a given ecosystem. In the case of the Black Sea, we can use the ecological pyramid to estimate the amount of plankton needed to sustain a 300kg dolphin.

The ecological pyramid consists of three trophic levels: producers (such as phytoplankton), primary consumers (such as zooplankton), and secondary consumers (such as small fish and dolphins).

To calculate the amount of plankton needed to sustain a 300kg dolphin in the Black Sea, we can use the 10% rule, which states that only about 10% of the energy from one trophic level is passed on to the next. This means that for every 1kg of dolphin, there needs to be 10kg of the dolphin's prey at the trophic level below it.

Using the 10% rule, we can calculate the amount of plankton needed to sustain a 300kg dolphin in the Black Sea.

First, we need to consider the trophic levels in the Black Sea ecosystem. Phytoplankton are the primary producers, and zooplankton are the primary consumers that feed on phytoplankton. Dolphins, as secondary consumers, feed on small fish and other marine organisms.

According to the 10% rule, if a 300kg dolphin needs 10 times its weight in prey, it would require 3000kg of prey. Since the dolphin's prey consists of small fish and other marine organisms, we can estimate that a significant portion of the prey's diet comes from zooplankton.

Therefore, to sustain a 300kg dolphin in the Black Sea, there would need to be a substantial amount of zooplankton available, likely in the range of several thousand kilograms.

This estimation is based on the ecological pyramid and the 10% rule, which are fundamental principles in ecology for understanding energy transfer and biomass distribution in ecosystems.
