Questions and CORRECT Answers
Define nutrition in your own words. - Correct Answer- Nutrition is the study of the processes
that occur to take nutrients from food that is consumed and utilize it for the healthy growth
and maintenance of living organisms.
How do plants provide the essential link between the soil and animal life? - Correct Answer-
Plants provide the link between soil and animal life because they obtain their nutrients from
products (such as water, nitrate, etc.) which are found in the soil, and they provide nutrients
to animals and other organisms.
Define the term nutrient. - Correct Answer- A nutrient is an element that is part of a diet
which aids in growth and life processes.
What are the six classes of nutrients? - Correct Answer- The six classes of nutrients are water,
proteins/amino acids, carbohydrates, lipids, vitamins, and inorganic elements (minerals).
Which nutrients provide energy? - Correct Answer- Lipids, carbohydrates, and the carbon
skeleton of amino acids provide energy.
Why must "essential" nutrients be included in the diet? - Correct Answer- Essential nutrients
must be included in the diet because they're nutrients that can't be made by the body.
How have models helped nutritional science develop? - Correct Answer- Since finding
information on certain target species is difficult due to cost, ethics, or time, scientists
substitute them with models to expand their knowledge about nutrition.
Why doesn't nutrition have the precision possible with some physical sciences? - Correct
Answer- Precision isn't possible in nutrition because no two animals are completely similar.
There are many variables that affect the diet of different animals such as their environment
and desired purpose of the animal.
Who was Antoine Lavoisier and what is his significance to nutrition? - Correct Answer-
Founder of the science of nutrition. He recognized the need for protein, fat, and
carbohydrates and energy utilization.
, Compare and contrast the definition of ration with that of diet. (Be careful: I ask for
comparison and contrast, so don't just define them.) - Correct Answer- Ration is the amount
of food fed a day, while diet refers to the different feedstuffs (material/ingredients) used to
give to supply nutrition. Both have to deal with what's given to the animals to supply
nutrition except that ration refers to the amount and diet to the ingredients themselves.
Are the nutrients required by plants and animals the same? Why? - Correct Answer- Plants
and animals do not require the same nutrients. --Plant's nutrient requirements are simple since
they mainly require Nitrogen and inorganic elements, along with others and requirements are
similar between all plants. Plants are able to obtain most of their nutrients through the soil
and photosynthesis.
-animals require more nutrients depending on their age and species and they aren't able to
synthesize their own nutrients like plants can.
Read the section "Composition of Animal Feed" on text pp. 6--8. Select the five most
important pieces of information from the section and paraphrase them. List them in order
with the most important first. - Correct Answer- -Some of the components that make up feed
can be insoluble, indigestible, and can also be toxic. Any nutrient, if ingested in large
amounts, can be toxic to the animal.
-The majority of animal feeds contain protein which can be complex and will vary in size,
solubility, etc.
-Animals require lipids which are usually found in the form of fatty acids, linoleic/linolenic
acids, and fat-soluble vitamins.
-Glucose is the form of carbohydrates that is required by all animal cells for energy.
-Certain animals require inorganic (mineral) elements for specific functions, but in general,
mineral elements have no known function.
What factors affect the composition of the animal body? - Correct Answer- There are many
factors that can affect the composition of the animal body. The main factors are age and
changing fat content. Certain animals have a higher fat content depending on the activity they
tend to engage in (athletic vs hibernating). For example, the composition of a terrestrial
animal is going to be different from that of an aquatic one. Age affects the composition of the
animal body due to the mineral composition during different stages of life/growth. As an
animal grows, the bone mineral content increases.
What are the "extra" essential amino acids needed by poultry? For what purpose are they
required? - Correct Answer- The extra essential amino acids that poultry need are glycine,
proline, and serine. These enzymes are required to promote the growth of the animal.
