Biology: Science for Life weaves a compelling storyline throughout each chapter, grabbing your attention with current high-interest topics such as genetic testing, global warming and the Zika virus. With this approach, you'll learn the relevant biological principles behind each story and how science can help answer complex questions.
27 wrz 2021 · Energy is exchanged between them and their surroundings as they use energy from the sun to perform photosynthesis or consume energy-storing molecules and release energy to the environment by doing work and releasing heat.
Here, I outline the various sources of energy that different life-forms use. The most fundamental division of life from an energy perspective is that between self-feeders that can utilize non-biological forms of energy such as light (autotrophs) and those that feed on other organisms (heterotrophs).
15 wrz 2020 · New and updated stories in the 6th Edition make biology concepts relevant and interesting by connecting them to stories you see in the news and decisions you make every day. And with The Big Question feature, you'll practice using data to critically evaluate information.
The process of photosynthesis, which usually begins the flow of energy through life, uses many different kinds of energy-carrying molecules to transform sunlight energy into chemical energy and build food.
Virtually every task performed by living organisms requires energy. Nutrients and other molecules are imported into the cell to meet these energy demands. For example, energy is required for the synthesis and breakdown of molecules, as well as the transport of molecules into and out of cells.
