Grassland biome has grasses as a dominant vegetation. It requires periodic fire, intensive grazing and mowing for its maintenance. Grazing animals stimulates plants to grow. It triggers biological activity and nutrient exchanges. Due to periodic fire, the nutrients from the dead animals are turned to ash very quickly and are available to plants.

Texts: 1. Write a summary of the article of at least 150 words that will convince us that you read the article. Be sure to include the roles of Fanny Hesse, Pasteur and Koch and their contribution to the germ theory. Late 1800s EUROPE Microbes caused disease CHAPTER THREE Germ theory changes everything For 200 years, a gathering chorus of voices raised tentative versions of the idea that animalcules, or germs, cause disease. Proponents Robert Koch of humoral medicine, and of filth theory, succeeded for a time in shouting them down. But in the 19th century, as microscopes became more powerful and more widely distributed, bypassing conventional medical beliefs. One of the other researchers began to open up the world his studies in the os started with the mundane of microorganisms. The idea that the specific goal of helping a local manufacturer identify microorganisms could cause specific infectious diseases - and even decimate human societies - became more persuasive. History tends now to honor two men, Louis Pasteur and Robert Koch, as the fathers of germ theory and forget the chorus whose work they built on. That's partly because human nature responds more to a few great names than to the cumulative and collaborative way most discoveries happen. But Pasteur and Koch were also masters of experimental science, meticulous about methods, and brilliant at choosing the right path from one experiment to the next. 2. After reading this article, do you think the germ theory changed history? Explain your answer. You might also want to read related material in your textbook. You also might find Google or YouTube searches help you fill out your answer. (100 words) After reading this article, it is clear that the germ theory changed history. The article highlights the contributions of Fanny Hesse, Pasteur, and Koch to the development of the germ theory. Fanny Hesse played a crucial role in the development of agar as a medium for growing bacteria, which revolutionized the field of microbiology. Pasteur and Koch, considered the fathers of germ theory, conducted groundbreaking research that demonstrated the role of microorganisms in causing disease. Their discoveries paved the way for advancements in medicine and public health, leading to the development of vaccines, antibiotics, and improved sanitation practices. The germ theory fundamentally changed our understanding of disease transmission and prevention, and its impact on history cannot be overstated.
