OBJECTIVE FORESTRY

Detailed explanation-1: -Earthworms play a crucial role in maintaining healthy soils by their intense burrowing activity. The earthworm species that live in the soil move through it, eating the food they find there and mixing the soil particles with pieces of dead leaves.

Detailed explanation-2: -Hookworm, Ascaris, and whipworm are known as soil-transmitted helminths (parasitic worms). Together, they account for a major burden of disease worldwide. An estimated 807-1, 221 million people in the world are infected with Ascaris lumbricoides (sometimes called just “Ascaris”).

Detailed explanation-3: -Worms make soil and are natural soil tillers. They can eat their weight in dirt each day. One acre of soil may contain up to one million worms. Those worms can produce around 700 pounds of castings each day.

Detailed explanation-4: -Living organisms present in soil include archaea, bacteria, actinomycetes, fungi, algae, protozoa, and a wide variety of larger soil fauna including springtails, mites, nematodes, earthworms, ants, and insects that spend all or part of their life underground, even larger organisms such as burrowing rodents.
