Amphibians use different respiratory organs at distinct phases, i.e. gills in the tadpole stage and after that pores and skin and lungs in the Grownup phase.

Animals are heterotrophic, which means they count on other organisms—vegetation and/or other animals—for his or her food stuff, as they cannot synthesize their particular food items as crops do via photosynthesis.
