About This Chapter
NJBCT: Matter and Energy Transformations - Chapter Summary
Use this chapter on matter and energy transformations to continue expanding your knowledge of biology as you get set for the NJBCT assessment. These text and video lessons outline the significance of free energy and matter. In addition to discussing two kinds of cellular respiration, they review how to recognize a synthesis reaction. Explore topics such as energy conservation, food webs, food chains and photosynthesis so that by chapter's end, you can:
- Understand how elements produce compounds and molecules
- Write a decomposition reaction
- Discuss how free energy and matter are necessary to the growth and reproduction of living things
- Explain the cycling of nitrogen and carbon
- Understand the process of energy conservation and the law of conservation of matter
- Define food webs and food chains
- Describe energy transfer and efficient dieting
- Explain photosynthesis and list the environmental elements that influence the process
- Explore cellular respiration processes and discuss their relationships with photosynthesis
Through the narration and expertise of the lesson instructors, you could master these topics and provide correct answers to the NJBCT examination's relevant questions. The entertaining videos are between five and ten minutes long, and they include graphics, definitions and examples. Watch and learn from your mobile device or wired computer. You can submit your questions on the Dashboard and explore the bold terms within the lesson transcripts.
NJBCT: Matter and Energy Transformations Chapter Objectives
There are two kinds of questions on the NJBCT test: multiple-choice and performance assessment tasks, for which students provide lengthy written answers to problems. The examination includes five content areas. You'll answer questions on the Organization and Development, Matter and Energy Transformation, Interdependence, Heredity and Reproduction and Evolution and Diversity sections. Apply what you've learned throughout this chapter on the Matter and Energy Transformation portion of the test. A periodic table of elements is provided for your reference during the assessment.
1. How Compounds and Molecules Are Built From Elements
Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.
2. Decomposition and Synthesis Reactions
Learn how to write, identify and predict the products of simple synthesis and decomposition reactions. This includes the composition of reactions with oxygen, of two metals, and of metals with nonmetals, as well as the decomposition of metal carbonates, metal chlorates and metal hydroxides.
3. Living Systems Requirement for Free Energy and Matter
Free energy and matter are required by all living things in order to grow, reproduce, and maintain biological processes. Additionally, free energy and matter must also be recycled through the environment in order to remove dead material and allow for new growth.
4. Cycles of Matter: The Nitrogen Cycle and the Carbon Cycle
Matter is constantly cycled between living and nonliving parts of the environment. Processes like photosynthesis and nitrogen fixation allow the carbon and nitrogen cycles to regenerate needed substances by recycling Earth's atoms.
5. What is Energy Conservation? - Definition, Process & Examples
This lesson will explain what the conservation of energy principle is and why it matters, using some real-life examples of how it works in our day-to-day lives. A short quiz will follow.
6. Law of Conservation of Matter: Definition & Matter
In this lesson, we'll learn the definition of the Law of Conservation of Mass, sometimes called the Conservation of Matter. This lesson explores the discovery of this important principle and covers a few examples of how it works.
7. What is a Food Web? - Definition & Explanation
This lesson will provide a definition of a food web, as well as describe its parts and discuss examples of different types. It will also explain the transfer of energy through a food web.
8. Food Chains, Trophic Levels and Energy Flow in an Ecosystem
In this lesson, you'll learn about food chains, food webs, and the different roles that organisms play in an ecosystem. You'll also learn about how energy flows through an ecosystem.
9. Photosynthesis: Definition & Reactions
Some people may falsely assume plants to be weaker than animals. However, plants and a few other organisms harness light energy from the sun to feed the rest of us. This lesson will introduce you to how they do it.
10. Cellular Respiration: Energy Transfer in Cells
Watch this short video to learn the basics about converting organic compounds into ATP, also known as cellular respiration. We'll look at an overview of the process.
11. Efficient Dieting: Formula & Energy Transfer
Are you trying to gain or lose weight? In this lesson, we will discuss a simple formula to estimate how many calories you expend in a day. We'll also talk about a few dietary factors that contribute to weight gain or loss.
12. Environmental Factors That Impact Photosynthesis
What is photosynthesis? Learn about the environmental factors that affect the rate at which photosynthesis happens. Then, take a quiz to test your understanding.
13. The Relationship Between Photosynthesis & Cellular Respiration
The ecosystems of the world are generally in balance with one another. Animals and plants live in mutually beneficial relationships. We will examine one of these relationships: the relationship between photosynthesis and cellular respiration.
