Nutrition Trivia Quiz

Answer: Proboscis

A butterflies uses its proboscis to suck up the nectar from flowers. This is a type of holozoic nutrition. Holozoic nutrition is a type of nutrition where one organism feeds upon another organism and draws nutrition.

Answer: phagocytosis

The single-celled amoeba has no particular shape. Pseudopodia also help it move. The word comes from the roots 'pseudo' meaning 'false' and 'podium' meaning 'foot'. After engulfing, the food vacuole goes to the nucleus, where it is digested with the help of enzymes.

Answer: ingestion, digestion, absorption, assimilation, egestion

Ingestion is the process by which an organism procures or gets food.
Digestion is the process by which the organism breaks down the complex food molecules into simpler, more soluble ones.
Absorption is the process in which the digested food enters the bloodstream.
Assimilation is the process by which the digested and absorbed food is utilized by the organism.
Egestion is the process by which undigested food is expelled from the body.

Answer: rumen, reticulum, omassum, abomassum

Cows have a four-chambered stomach to digest cellulose - the substance the cell walls of plant cells are made of. In the first chamber (the rumen), bacteria and other microorganisms break down the food. Then the food is sent to a second chamber called the reticulum after which the half-digested food is sent back to the mouth.

Then the ruminants chew the cud. Then the food bypasses the first two chambers and enters a third chamber called the omassum where it is broken down into smaller pieces. Then, in the fourth chamber called the abomassum, enzymes act upon the food and digestion is completed.

Answer: alga

A lichen is an example of symbiotic nutrition. It consists of a fungus and an alga who cooperate and live with each other, both of them getting mutual benefit. The fungus, which is the mycobiont organism, supplies the alga with water and minerals that it draws from the soil.

The alga can photosynthesize. The alga, the phycobiont organism, prepares food out of the materials and supplies the fungus with food too.

Answer: vitamins

Vitamins are an integral part of the human diet as well. Vitamins A, D, E and K are soluble in fat. Vitamins B (and its sub vitamins) and C are soluble in water. They perform vital functions in our bodies.

Answer: diastema

Moreover, most of the teeth of herbivores are in the sides of the cheeks. Only the incisors, used for cutting food, are at the front. However, carnivores have very well-developed canines for tearing flesh.

Answer: tentacles

A hydra uses its tentacles around its mouth to engulf small aquatic organisms around it. Then it kills those organisms with its stinging cells. After this, it draws nutrition from them. This is an example of predatory nutrition.

Answer: leaves

Those plants ingest insects to obtain nitrogen for making proteins. Though the air is 78% nitrogen, plants do not have the required enzymes to take it in. Insectivorous plants take in nitrogen in the form of nitrates, nitrites, etc. from insects. Some examples are pitcher plant, sundew and Venus flytrap.

Answer: Dog

An animal's metabolic rate is the rate at which it 'burns' its food to release energy. Considering the rate for humans as 1, the rate for dogs is 1.57, the rate for sheep is 1.05 and the rate for horses is 0.52.
