Life cycle and growth curve of a butterfly, frog and bean plant

Pick an organism and press Play: the life-cycle stages (egg → caterpillar → pupa → butterfly; egg → tadpole → frog; seed → seedling → mature plant flowering and fruiting) light up one by one over the days, alongside a growth curve where size rises then levels off. Drag the temperature and nutrition sliders right on the picture: a favorable temperature (about 25–30 °C) shortens the life cycle, while too cold or too hot stops development; too little food means slower, smaller growth.
