Chapter 37.3, Problem 1CC
Summary Introduction
To explain: Why a study of the rhizosphere is needed to understand plant nutrition.
Concept introduction: The rhizosphere is a region around the plant roots which contains a number of bacteria with which the root systems form a mutualism that is beneficial. These bacteria depend upon the plant’s sugars, proteins, and sloughed off cells as their primary source of food. In return, the bacteria help to create a nutrient-rich and more aerated place for the roots of the plants.

Can you tell…arrow_forwardYou have been hired as a public relations specialist to give invertebrates a good name. After all, they are much more than just creepy crawly bugs! Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
