Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

Effect of Nitrate and Phosphate Levels on the Growth of Algae

Nitrate and phosphate are useful as fertilizers in agriculture and gardening. Nitrate and phosphate aid agricultural production by producing more abundant crops. However, since the mass production of ammonia during the 1940's by way of the Haber process, it has been noted that a phenomenon known as “nitrate pollution” may occur. This pollution can be demonstrated by conducting this simple experiment. This experiment demonstrates two main ideas. The first is a test of what levels of nitrate and phosphate allow for optimum algal growth. The second demonstrates at which levels of nitrate and phosphate algal blooms may occur, causing harm to an aquatic ecosystem (Freeman, 2002).

0.0 stars

This lesson plan helps students understand the factors that affect water quality and the conditions that allow for different animals and plants to survive. Students will look at the effects of water quality on various water-related activities and describe water as an environmental, economic and social resource. The students will also learn how engineers use water quality information to make decisions about stream modifications.

Polysaccharides in the water help shape bacterial communities after algal blooms

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"The global carbon cycle is a critical process that moves carbon from the atmosphere into plant and animal materials and then back into the atmosphere. Two major parts of this cycle are microalgae blooms in the oceans and bacterial blooms that occur when the microalgae die. Microalgae are made mostly of polysaccharides, so polysaccharide breakdown is an important aspect of the bacterial blooms. To learn more bloom dynamics, researchers recently sampled the water at 30 time points during a two-phase spring bloom in the German Bight. They were able to reconstruct 251 genomes of planktonic bacteria, 50 of which were particularly abundant and active. These 50 genomes represented many polysaccharide-degrading bacteria. β-Glucans and α-glucans were the most abundant and actively metabolized polysaccharides in the water. The bacteria degraded both types of glucans throughout the whole bloom, but the expression of α-glucan degrading genes peaked at the start of the second phase..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.
