Explanation:
when the female frogs lays her eggs directly in the water and fertilized eggs are hatched into aquatic tadpoles, on maturity they acquire legs and lungs. tadpoles have tails which is lost during the metamorphosis and the frogs also acquire the carnivorous tastes.
As evident that the male clasps the female from her back and releases the sperm through which the fertilized eggs are laid into water by the female frogs, mature frogs develops the trait of tetrapod. A Tetrapod animal is the one having four pods or four legs. A complete metamorphosis occurs in the life cycle of the frog.
Answer:
Cooperative. (Ans. B)
Explanation:
Cooperative interaction is also called as mutualistic interaction. It is defined as an interaction where One that benefits the recipient other than the performing the behavior.
So, in this study a layer of purple photosynthetic bacteria is using sulfide as an electron source. Sulfide is oxidized by these bacteria, which grow in a layer above sediment from which you have isolated sulfate-reducing bacteria that generate sulfide during anaerobic respiration.
These bacteria's are showing cooperative interaction between each other. Where one species producing a product (sulfate reducing bacteria) that serves as food for other species (photosynthetic bacteria).
