Body bovine tapeworm consists of a head, segments and tail. 2. Antennae and eyes are located on the head. 3. The outside of the body is covered with a layer of chitin. 4. They live in the intestines of the host organism, where there are many nutrients. 5. Digestive system is absent, nutrition occurs through the absorption of substances over the entire surface of the body.

Once in the water, microscopic larvae equipped with cilia develop from the eggs. They penetrate the body of the small pond snail mollusk, in which they grow, multiply, and tail larvae appear. These larvae leave the mollusk, actively swim in the water, then attach to plants, cast off their tail, and become covered with a thick shell - a cyst is formed. With grass or water, the cyst enters the cow's intestines, where it develops into an adult worm. A person can become infected with liver fluke if he drinks water from a dirty pond.

Earthworms
The family of earthworms (Lumbricidae) from the class Oligochaeta consists of almost 170 species, and belongs to the phylum annelids– Annelides ( ).
For the first time on vital importance Earthworms in the formation of soil were indicated by Charles Darwin in his classic work “The Formation of the Vegetative Layer of the Earth by the Activity of Earthworms and Observations on Their Lifestyle.”
Darwin was the first to establish the biogenic nature of soils and was the first to show the significant role of animal organisms, primarily earthworms, in the process of soil formation. He was also the first to show, using the example of earthworms, how great value Ordinary and little noticeable phenomena play a role in the processes of soil formation, how enormous is the work performed in nature by insignificant organisms, if this work is carried out by them day after day for centuries and millennia.
Earthworms make up from half to three quarters of the total biomass of soil invertebrates and do a tremendous job of improving the health and fertility of the soil. Earthworms pass a large mass of dead plant matter through their intestines, in which the plant tissues are finally destroyed, digested and then mixed with the soil. Thanks to the activity of earthworms, compost “matures” faster, turning after their processing into free-flowing, friable, consisting almost exclusively of granular excrement of worms, environmentally friendly and extremely useful substance(humus), which is easily absorbed by plants.

C2. Using the content of the text “Class of Flukes”, answer the questions:

What is the significance of earthworms?

How do earthworms improve soil fertility?

C3. Describe the significance of bivalves in nature and human life? Give a detailed answer.
