Answer my questions

Dear student, (a) top layer of soil is formed by weathered rock materials. (b) terrestrial organisms live on the top layer of the soil. (C) False because tiger is not an aquatic animal. It is a land animal. (d) If the top layer of soil is infertile, then it will gradually expose the lower layer of soil, which is hard and rocky in nature. This type of soil is less fertile as it contains less humus. Continued soil erosion will make the land barren or infertile. Thanks and regards
