Question

помогите решитьОдно растение василька голубого производит в среднем 1500 семян. Семена сохраняют всхожесть до 10 лет. Определите запасы семян этого сорняка в почве после 3 лет засорения им посевов на одном поле со средней численностью 3 растения на 1 м3.

Answer 1

Решение
Один цветок дает 1500 семян в год. у нас спрашивается про 3 года
1) 1500*3=4500 семян дает один василек за 3 года.
По условию дано 3 василька
2) 4500*3=13500 семян дадут 3 василька за 3 года.
Ответ: 13 500 семян составляет запас семян в почве за 3 года.

Answer 2

Calculation of Seed Reserves

To determine the seed reserves of the blue cornflower after 3 years of contamination in the fields with an average density of 3 plants per cubic meter, we need to consider the following information:

- Each blue cornflower plant produces an average of 1500 seeds. - The seeds maintain their viability for up to 10 years.

To calculate the seed reserves, we can use the following steps:

1. Calculate the total number of seeds produced by a single plant over 3 years: - Each plant produces 1500 seeds per year. - Therefore, in 3 years, a single plant would produce 1500 x 3 = 4500 seeds.

2. Calculate the total number of seeds produced by all the plants in one cubic meter over 3 years: - The average density is 3 plants per cubic meter. - Therefore, in one cubic meter, the total number of seeds produced would be 4500 x 3 = 13,500 seeds.

Therefore, after 3 years of contamination in the fields with an average density of 3 plants per cubic meter, the seed reserves of the blue cornflower would be approximately 13,500 seeds.

Please note that the calculation assumes that all the seeds produced are viable and remain in the soil without any loss or decay.
