Joints and Muscles work together to allow movement in an organism. A joint is formed where two bones meet. Muscles are responsible for movement in the human body.
HSB Note-Food Chains and Food Webs
Food Chains and Food Webs represent the biological hierarchy of organisms within a single ecosystem. A food chain is a succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and in turn, is preyed upon by a higher organism.
HSB Note-Photosynthesis
Photosynthesis is a fundamental principle in Biology. It is the process by which the cycle of life begins and without it the entire animal kingdom would starve. Photosynthesis is the process by which green plants and some other organisms use sunlight energy to convert carbon dioxide and water into glucose and oxygen.
HSB Note- Characteristics of Living Things and Cells
Characteristics of living things and Cells are the first two topics we learn in Human and Social Biology. Biology is the science of life or
