Learning Guide: Physiology 2 Nutrition
Bill Activity #51
To Think About: Why do organisms need to acquire nutrients? How do organisms acquire nutrients? What happens if
organisms are unable to acquire nutrients?
1st Learn About: Use text and prezi presentation Nutrition to answer the following questions in your BILL
Ch. 31: Fungi; Ch. 37: Soil and Plant Nutrition; Ch. 41: Animal Nutrition Campbell’s Biology 9th edition
Part I: Introduction, Fungal, and Plant Nutrition
Questions to Answer:
1. Explain the role of nutritional systems in contributing to the maintenance of homeostasis in organisms.
2. Explain the process of fungal nutrition.
3. If autotrophs can make their own food, why do they have any nutritional requirements?
4. How are nutrients absorbed at the roots of plants?
5. How do plants acquire nitrogen? Why is nitrogen necessary for plants?
6. Explain the purpose of the adaptations found in carnivorous plants and parasitic plants.
Make Sure You Can:
Explain why organisms require nutrients, how they accomplish the process involved in nutrition, and the consequences
of malnutrition.
Explain how the structure and function of plant organs contribute to plant nutrition.
Describe the roles of symbiotic relationships in plant nutrition.
Part 2: Animal Nutrition
Questions to Answer:
1. Where do the four major stages of nutrition (ingestion, digestion, absorption, elimination) occur in a human?
2. Create and fill in the following chart in your BILL
Organ
Example(s) of Chemical Digestion
Example(s) of Physical Digestion
Mouth
Stomach
Small Intestine
3. Explain how food is absorbed in to the mammalian body.
4. Diagram the blood glucose level feedback loop.
Make Sure You Can Explain:
 The structure and function of all parts of the mammalian digestive system.
 How the structure and function of all organs in the mammalian gastrointestinal tract contribute to nutrition of a
mammal.
 Where in the gastrointestinal tract specific types of macromolecules begin to be broken down.
 The roles of symbiotic relationships in the nutrition function of the large intestine in mammals.
 How dentition, obesity, and the structure of the gastrointestinal tract in mammals can serve adaptive functions.
 How the mammalian digestive system demonstrates the ideas of compartmentalization and cooperation among
organs.
 The causes, effects, and treatments of the disorders demonstrated in the presentation.
