Learning outcomes and their assessment

Students obtain knowledge on ecosystem of grassland components, structure, outward and internal connections, ecosystems modeling, interaction of ecosystem of grassland organisms, food matter and energy stream and turn in a biosphere. Students are skilled to evaluate role of ecosystem of grassland yield formation, they are skilled to identify ecosystem components. The students acquire skills through the latest information technologies and information to navigate, publicly perform, present discuss their own professional findings. In result, students are competent in grassland ecosystems and management of agrobiocenosis formation process, organization and use of pasture. To study scientific literature and to carry out further self - education on topics included into the study course.
