Answer (1)

Types of Heterotrophic Nutrition : There are three main types of heterotrophic nutrition:
a. Holozoic Nutrition : This involves consuming and internally processing solid food particles. Humans and many animals have this type of nutrition.
b. Saprophytic Nutrition : Organisms obtain nutrients by absorbing dissolved organic matter, usually from dead and decaying material. Fungi and some bacteria exhibit this type.
c. Parasitic Nutrition : Parasites obtain nutrients directly from the living host. They often harm the host in the process. Examples include tapeworms and fleas.

Egestion : Egestion is the process of expelling undigested food material and waste products from an organism's body. This is commonly known as defecation in humans.

Types of Teeth : There are four different types of teeth in the human mouth:
a. Incisors : These are the front teeth used for cutting food.
b. Canines : These are the pointed teeth used for tearing food.
c. Premolars : These are used for crushing and grinding food.
d. Molars : These are used for grinding food and are larger than premolars.

Function of the Throat : The throat, or pharynx, functions as a passageway for food and air. It connects the mouth and nasal passages to the esophagus and larynx, guiding food to the digestive system and air to the respiratory system.

Part of the Digestive System Receiving Waste, Undigested Food : The part of the digestive system that receives the waste, undigested food is the large intestine, also known as the colon.

Food Vacuole : A food vacuole is a membrane-bound organelle found in some cells, particularly in single-celled organisms like amoebas and some complex cells. It is used to store and digest food particles.
