Nutrition and Energy Transfer in Organisms

10 Questions

Match the following terms with their descriptions:

Energy = Needed for maintenance processes to prevent damage and break-down Nutrition = Process of transferring energy from food outside the body to inside Respiration = Process of acquiring oxygen from outside and using it to break-down food sources Oxidising-reducing reactions = Common chemical means used to break-down molecules

Match the following statements with the correct explanation:

Body growth = Requires additional raw material from outside the organism Carbon-based molecules = Most food sources are carbon-based due to life depending on them on earth Environmental control = Organisms cannot control the energy sources in their environment Chemical reactions = Necessary for converting energy sources into usable forms for cellular needs and growth

Match the following characteristics with their significance:

Complexity of carbon sources = Determines the type of nutritional processes different organisms can use Outside energy sources = Varied due to the lack of control by individual organisms Uniform source of energy = Needed for maintaining living structures and supporting growth Molecular movements = Require a common source of energy derived from external sources

Match the following processes with their roles:

Breaking down or building up energy sources in the body = Conversion to a uniform source of energy for cellular needs Acquiring oxygen for cellular needs = Part of the respiration process in organisms Using oxygen in food break-down = Involves oxidising-reducing reactions in many organisms Chemical reactions in the body = Essential for breaking down molecules and supporting growth

Match the following functionalities with their importance:

Maintaining living structures = Requires various molecular movements fueled by a common energy source Supporting body growth = Necessitates acquisition of additional raw material from outside Conversion of energy sources = Needed to provide usable forms for cellular functions and growth Use of oxygen in metabolism = Critical for breaking down food sources into energy for cellular needs

Match the following with their functions in multi-cellular organisms:

Specialised tissues = Uptake of food and oxygen Transportation system = Carrying food and oxygen Excretion = Discarding waste by-products outside the body Simple diffusion = Not meeting the requirements of all cells

Match the following with their roles in a multi-cellular organism's body design:

Specialised tissues = Performing specific functions Transportation system = Moving substances between different parts of the body Simple diffusion = Not sufficient for all cells Excretion = Removing harmful waste by-products

Match the following with their importance in multi-cellular organisms:

Specialised tissues = Uptake of food and oxygen Transportation system = Carrying nutrients to all body parts Excretion = Getting rid of harmful waste products Simple diffusion = Limited effectiveness for all cells

Match the following with their necessity in complex body designs:

Specialised tissues = Required for specific body functions Transportation system = Needed to distribute essential substances Excretion = Essential for removing harmful by-products Simple diffusion = Inadequate for all cells' needs

Match the following with their functions in an organism's growth:

Specialised tissues = Uptake of essential nutrients Transportation system = Distribution of necessary substances Excretion = Elimination of waste materials Simple diffusion = Insufficient for larger body sizes
