Compare the soil of open land (without grasses or plants) with that of land of garden/river bank/parks shaded by trees. Fill the following table: How is the soil Plant-less soil Soil with plant Whether the soil is hard or soft Whether the soil is more or less porous How many types of small animals are there? Whether the soil is loose or not loose Whether the soil is wet or dry Whether the soil is extremely hot or cold (at noon)

Soil is the uppermost fertile layer of the Earth that is used for agricultural purposes. Trees and soil contribute numbers of benefits to each other, or we can say that trees and soil mutually benefited each other. How is the soil Plant-less soil Soil with plant Whether the soil is hard or soft Hard Soft Whether the soil is more or less porous Less porous More porous How many types of small animals are there? Animals are absent Small living creatures, such as earthworm Whether the soil is loose or not loose Not loose Loose Whether the soil is wet or dry Dry Wet Whether the soil is extremely hot or cold (at noon) Hot Cold Plants absorb water and minerals from the soil for photosynthesis. The absorption of water remain continuous due to the transpiration through minute pores called the stomata. The water keeps the soil soft, porous, wet, and main the temperature of the soil. The porous soil facilitates the exchange of gases and is a suitable habitat for several small living beings.
