Question

What damage or harm do ectoparasitic and endoparasitic causes to animals?

Answer 1

Hint: Parasites are defined as living beings which depend on other organisms. It is classified as two organisms. They are ectoparasitic and endoparasitic. Parasites are called as a carnivore if it is living with the animals and it is called as the herbivores if it living with the plants. Giardia lamblia is an example of an endoparasite. It is an anaerobic protozoan which affects or infects humans. Mosquito is an example for the ectoparasitic organism.

Complete answer:
Parasitism is the type where one of the partners is benefited either outside or inside of the body of the hosts. So, they get free accommodation and food from the host. So, the host's nutrients will be reduced. Some of the parasites may cause disease for the host also. Ascariasis disease is caused by the endoparasites of the intestine. Wuchereria causes Elephantiasis or filariasis. It is called endoparasites. It lives in the lymphatic vessels. This lymphatic vessel is in the lower limbs. Perfect example of ectoparasite is lice or ticks in dogs. They get a lot of energy and nutrients from the host. Some of them sucks the blood from their host also. Endoparasites are the more dangerous one. It severely attacks the host. Ectoparasites weaken the host by sucking nutrients, blood and proteins from the host. Feeding parasites destroyed the tissue of the hosts. Lots of physical damage will occur by parasites.
Mechanical pressure is produced by the animals by the Toxocara canis. Tissue destruction is made by the Rhipichephalis. Running of flies around the animals may reduce the energy of the animals. It results in weight loss also. Some flies will bite so it affects the tissue, causes bacterial infection and also the viral disease.

Note:
Ectoparasites live on the surface of the host and endoparasites live in the host. Ectoparasites are either temporary or permanent. But endoparasites are only permanent ones in the host. Ectoparasites have aerobic respiration and other one has anaerobic respiration. Ectoparasites produce less damage to the host compared to the endoparasites. Endoparasites do not have a digestive system.
