Nutrition is defined as the process of eating food to carry out different body functions necessary for the survival of organisms. The two main types of nutrition are autotrophic and heterotrophic. When an organism can prepare its own foods, such as plants, they are known as autotrophs and that type of nutrition is known as autotrophic nutrition. Therefore, our correct answer is the table below.
The term “autotroph” is derived from two Greek words auto (self) and trophe (nutrition). In autotrophic nutrition, an organism makes its own food from simple raw materials. Holozoic nutrition is a type of heterotrophic nutrition characterized by the ingestion and internal digestion of gaseous, liquid or solid food particles, which are usually carried out by animals. In holozoic nutrition, complex organic substances are ingested (absorbed) without being broken down or broken down.
This type of nutrition is found mainly in non-parasitic animals, simple like amoeba and complex like humans. Holozoic nutrition is a type of heterotrophic nutrition characterized by the ingestion and internal digestion of gaseous, liquid or solid food particles. One of these groups is that of the chemotrophs, “chemo”, which refers to their method of nutrition, which consists of converting one type of chemical substance into another, such as the bacteria in Figure 2.Many parasites are associated with diseases, since, often, in the process of obtaining their nutrition, the host loses part of its own source of nutrition or is harmed in the process. The leeches, shown in the image, attach themselves to the body of another organism and obtain their nutrition by consuming part of that organism's blood.
Other molecules that can be obtained through nutrition are fats and minerals, which are essential for isolation, protection and the multiple functions that maintain the normal functioning of the body. Heterotrophs are organisms that obtain their nutrition by consuming other living organisms or that once lived. The parasite, for example, Plasmodium falciparum, responsible for causing malaria, will obtain its nutrition at the expense of the host. Nutrition in single-celled organisms, such as the amoeba, involves ingestion through the cell surface, digestion, and egestion.
The information in the question tells us that leeches attach themselves to the body of another organism and consume their blood for nutrition.
