Question

При каких условиях сохранится плодородие степей, если в течение года: а) выпадают обильные осадки, б) осадки отсутствуют в) выпадает не большое количество осадков??

Answer 1

Плодородие почвы сохранится,если выпадение осадков будет в норме.Т.е ближе к ответу в). Если будет выпадать большое кол-во осадков-почва перенасытится и её просто размоет,а если осадков вообще не будет,то засуха будет.

Answer 2

Conditions for Maintaining Fertility in Steppes

The fertility of steppes, which are grassland ecosystems characterized by a semi-arid climate, can be influenced by the amount of precipitation received throughout the year. Let's explore the conditions under which fertility can be maintained in steppes based on different precipitation scenarios:

a) Abundant Precipitation: If steppes receive abundant rainfall throughout the year, it can help maintain the fertility of the soil. Adequate moisture supports the growth of vegetation, which in turn contributes to the accumulation of organic matter in the soil. This organic matter enriches the soil with nutrients and enhances its fertility.

b) Lack of Precipitation: In the absence of rainfall, steppes may experience drought conditions, which can negatively impact soil fertility. Without sufficient moisture, plant growth is limited, leading to reduced organic matter accumulation and nutrient availability in the soil. As a result, the fertility of the steppes may decline.

c) Limited Precipitation: When steppes receive a moderate amount of rainfall, but not an excessive amount, the maintenance of soil fertility depends on various factors. These include the ability of the soil to retain moisture, the presence of deep-rooted plants that can access water from deeper soil layers, and the adaptation of vegetation to the semi-arid conditions. These factors can help sustain the fertility of the steppes even with limited precipitation.

It's important to note that the fertility of steppes is influenced by multiple factors, including climate, soil characteristics, vegetation composition, and human activities. The interplay of these factors determines the overall fertility and health of the steppes.
