In which of the following soil types will a crab burrow easily: sand, silt or clay. give reasons for your answer

A crab can easily burrow in sand type of soil.

Explanation:

Crab is a living aquatic organism which is seen in areas of oceans, freshwater lakes etc. The region near the water is mostly composed of sandy soil due to interaction of the water and the soil continuously.

Sandy soil is very loose and easy to dig. Due to this reason it can be inferred that among sand, soil and silt, the crab can dig burrow easily in the sand than the soil types such as clay or silt.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
