Earthworm
A worm is a worm living in moist soil and wet air. It
feeds on organic matter and its digestive system runs along its split body. It
breathes through its skin. It has a nervous system consisting of two nodes
above the mouth. It digs and lives in a tunnel. Important for farmers, they are
based on improving the agricultural crop, forming more layers in the soil,
increasing organic matter and digging in the soil for water passage and
ventilation. Many people wonder how the earthworms feed and how they grow and
how they multiply. We will answer these questions in this article.
Feed the earthworm
The soil worm feeds on leaves falling from the trees;
it takes part of the paper and pulls it to its hole and feeds on it. The
earthworm favors the leaves of the carrots and cabbage from the rest of the
leaves. When the leaves are not available, feed the soil. If the soil is dried,
Which fills the hole and remove it from the other end on the surface of the
soil, and when the food slightly swallows the dry soil and spread across the
body without any sections.
Propagation of
earthworm
When the worm prepares to eject its eggs, the mucus
secretes around the os and moves back until the caliper is pushed forward and
resembles the cocoon in its formation. After the eggs hatch and the small worm
grows, And in turn can reproduce after two months and be fully grown, it is
worth mentioning that the earthworm is fertilized, that is, with male and
female reproductive organs.
Earthworm Breathing
As we mentioned previously, earthworms breathe through
their skin. They do not have a respiratory system. They exchange gases through
their skin and capillaries. The oxygen is chosen by hemoglobin, which is
dissolved in plasma and carbon dioxide and released when exiting the hole.
Earthworm shape
The basic form of the earthworm is a thin cylindrical
tube consisting of several sections, which is the dorsal pores which secrete a
substance that protects the surface of the worm from dehydration, mouth,
sections, and anus. Each cutter carries a little rough hair on the sides used
in movement and the outer part, The skin of the worm is a reddish brown color,
a layer of nerve tissue, two layers of muscle and a layer filled with a fluid
called the general cavity.
