Use of soil?

Soil is used for plant growth by providing nutrients, water, and support for roots. It is also used for construction, landscaping, and as a habitat for many organisms. Additionally, soil plays a key role in filtering and purifying water.


Where does ground water come from?

Groundwater comes from precipitation that infiltrates the soil and percolates through rocks to collect in underground reservoirs known as aquifers. As the water moves through the ground, it dissolves minerals and nutrients, making it an important source of drinking water for many communities worldwide.


Why are many tropical soils poor in nutrients?

Many tropical soils are poor in nutrients due to high rainfall that leads to leaching of nutrients, rapid decomposition of organic matter, and weathering processes that remove nutrients. Additionally, the high temperatures and year-round growing seasons in tropical regions contribute to faster nutrient uptake by plants, further depleting the soil of essential nutrients over time.


How are living organisms dependenyton the soi are organisms that live in water totally independent of soil as a resource?

Organisms in water are not dependent on soil as a resource since they obtain nutrients and resources directly from the water they live in. These organisms have adapted to utilize the resources present in aquatic environments, such as dissolved oxygen, minerals, and organic matter, to support their growth and survival. While soil is not essential for aquatic organisms, it plays a vital role in supporting terrestrial life by providing nutrients, water retention, and a habitat for many organisms.


What are some ways in which life on earth depends on water?

Life on earth depends on water for survival as it is essential for various biological processes such as photosynthesis, digestion, and transportation of nutrients within organisms. Water also helps regulate temperature on earth and provides a habitat for diverse ecosystems to thrive. Additionally, many organisms rely on water as a source of food and for reproduction.
