Question

ДАЮ 10 БАЛЛОВ! Используя знания экологии о трофических цепях, определите, сколько примерно потребуется травянистых растений, чтобы вырос один орёл-змееяд массой 2 кг? Пищевая цепочка: травянистые растения – полёвка – змея – орёл.

Answer 1

Ответ:

2000

Объяснение:

В пищевой цепочке потери составляют 90%

Следовательно, нужно 20 кг растений, чтобы мышей было 2 кг

Answer 2

Trophic Levels and Energy Transfer in Ecological Food Chains

In an ecological food chain, energy is transferred from one organism to another through different trophic levels. Trophic levels represent the position of an organism in a food chain, with each level representing a different group of organisms that share a similar feeding behavior. The primary producers, such as plants or algae, occupy the first trophic level. They convert sunlight into energy through photosynthesis and form the base of the food chain.

In this specific food chain you provided, the trophic levels are as follows: 1. Trophic Level 1: Grasses or herbaceous plants (travyanistye rasteniya) 2. Trophic Level 2: Field mouse (polevka) 3. Trophic Level 3: Snake (zmeya) 4. Trophic Level 4: Snake eagle (orël-zmeyeyad)

Each trophic level represents a transfer of energy, with energy decreasing as it moves up the food chain. This is due to the inefficiency of energy transfer and the energy lost as heat during metabolic processes.

Estimating the Number of Grasses Required for the Growth of a Snake Eagle

To estimate the number of grasses required for the growth of a 2 kg snake eagle, we need to consider the energy transfer efficiency between trophic levels and the energy requirements of each organism.

Unfortunately, the search results provided by You.com do not contain specific information about the energy transfer efficiency or the energy requirements of the organisms in this particular food chain. Therefore, it is not possible to provide an accurate estimation of the number of grasses required for the growth of a snake eagle.

However, it is important to note that the energy transfer efficiency between trophic levels is typically low, with only a fraction of the energy being transferred from one level to the next. This means that a large amount of energy is lost at each trophic level, resulting in a smaller amount of energy available for the growth and development of higher-level organisms.

Additionally, the energy requirements of organisms vary depending on factors such as their metabolic rate, activity level, and reproductive status. These factors can further complicate the estimation of the number of grasses required for the growth of a snake eagle.

In conclusion, without specific information about the energy transfer efficiency and energy requirements of the organisms in this food chain, it is not possible to provide an accurate estimation of the number of grasses required for the growth of a 2 kg snake eagle.
