A: Nutrition is the process of taking in food and using it for energy, growth, repair, and maintenance of the body. It is essential for all living organisms because cells need materials and energy to car

A: Autotrophic nutrition is a mode of nutrition in which an organism makes its own food from simple inorganic substances like carbon dioxide and water, using light energy and chlorophyll. Green plants ar

A: Most green plants are called autotrophs because they prepare their own food by photosynthesis. They use sunlight, carbon dioxide, water, and chlorophyll to make carbohydrates, which later help in form

A: Respiration is the whole chain of processes from inhalation of air to the use of oxygen in the cells. It is the process that helps living beings release energy from food for life activities.

A: Cellular respiration is the pathway or chain of chemical reactions by which cells release energy by breaking the chemical bonds of glucose molecules. It is an important part of respiration because it

A: Respiration is called a catabolic process because it breaks down complex food molecules into simpler substances and releases energy. In glucose breakdown, energy is released for body activities.

A: The circulatory system is the specialized transport system that carries materials quickly through the body. It is needed because simple diffusion and osmosis are too slow for large multicellular organ

A: The heart is located between the lungs and is protected by the rib cage. It is approximately the size of a fist.

A: The human heart has four chambers: two atria and two ventricles. The upper chambers are atria, and the lower chambers are ventricles.
