as sources of energy
Слайд 4Nutrition
Authotrophs – organic substances either as a result of photosynthesis (plants)
or chemosynthesis (some bacteria)
Heterotrophs-consumers that don’t produce organic substances (animals)

Слайд 5Growth
Metabolism –use of organic substances within the cells which gives
rise to energy production
Anabolic reactions – digested foods particles are absorbed the cell
Catabolic reactions –Ingested food is catabolized within the cell, providing energy and etc.
