The role of amphibians in nature and human life.

ROLE OF AMPHIBIANS IN NATURE:
– elements of circuits and power supply networks,
– participants in the cycle of substances in nature,
– units of biogeoceosis,
– are part of populations – units of evolution.
ROLE OF AMPHIBIANS IN HUMAN LIFE:
– the use of frogs for food (in French cuisine),
– amphibians – experimental animals,
– amphibians – objects of regeneration experiments,
– aesthetic value (creation of aquariums, terrariums),
– negative value: poisonous species of tropical frogs, allergy to amphibian skin gland secretions,
– destruction of mosquitoes,
– the use of the bactericidal properties of the skin glands (earlier, with the help of frogs, the shelf life of milk was extended without refrigeration).
