noro number of eggs where as cow and human beings​

Answer 1

Answer:

Parental care

Explanation: The fish and frogs lay more eggs than cows and human because they lack parental care to their young once hence there chance of survival is very low this will cause only few to reach maturity and reach reproductive age thus in order to ensure their specie does not go extinct they have to produce many eggs  while on the other hand human and cows have parental care to their young ones meaning the parent will take care of  their young ones until they are able to depend on themselves hence their chance of survival is high.
