Question

ПОМОГИТЕ! За год к Земле поступает 1024 дж солнечной энергии почти 33% отражается в космос 67% поглощаемой атмосферой и поверхностью земли.из всей энергии только 0,2% используется во время фотосинтеза. 1.Рассчитать, сколько солнечной энергии используют растения за год? 2. рассчитайте, сколько энергии передается по всем трофическим цепям биосферы к консументам 2 порядка, если ее потери на каждом уровне составляют 10%

Answer 1

1. 1024 * 0,2% = 2,048 Дж потребляет растение
2. 2,048 - растения / продуценты
2,048 : 10 = 0,2048 консументы 1ого порядка
0,2048 : 10 = 0,02048 консументы 2ого порядка

Answer 2

Calculation of Solar Energy Used by Plants in a Year

To calculate the amount of solar energy used by plants in a year, we need to consider that only 0.2% of the total solar energy is used during photosynthesis. Given that 33% of the solar energy is reflected into space and 67% is absorbed by the atmosphere and Earth's surface, we can calculate the amount of solar energy used by plants as follows:

1. Calculate the solar energy absorbed by the atmosphere and Earth's surface: - Solar energy absorbed = 67% of total solar energy - Solar energy absorbed by the atmosphere and Earth's surface = 67% * 1024 J

2. Calculate the solar energy used by plants during photosynthesis: - Solar energy used by plants = 0.2% of solar energy absorbed by the atmosphere and Earth's surface

Let's calculate these values:

1. Solar energy absorbed by the atmosphere and Earth's surface: - Solar energy absorbed = 67% * 1024 J = 685.28 J

2. Solar energy used by plants during photosynthesis: - Solar energy used by plants = 0.2% of 685.28 J - Solar energy used by plants = 0.002 * 685.28 J

Therefore, plants use approximately 1.37 J of solar energy in a year.

Calculation of Energy Transferred in Trophic Levels

To calculate the energy transferred in trophic levels, we need to consider that there is a 10% loss of energy at each trophic level. Let's assume that the initial energy input at the first trophic level is 100 units. The energy transferred to the next trophic level can be calculated as follows:

1. Energy transferred to the next trophic level: - Energy transferred = 90% of the energy at the previous trophic level

To calculate the energy transferred to consumers of the second order, we need to consider the energy transferred from the first trophic level to the second trophic level:

1. Energy transferred from the first trophic level to the second trophic level: - Energy transferred = 90% of the energy at the first trophic level

Let's calculate these values:

1. Energy transferred to the next trophic level: - Energy transferred = 90% of 100 units = 90 units

2. Energy transferred from the first trophic level to the second trophic level: - Energy transferred = 90% of 100 units = 90 units

Therefore, the energy transferred to consumers of the second order is approximately 90 units.

Please note that these calculations are based on the assumptions provided and may not reflect the exact values in nature.
