Answer: Fishes
Explanation:
A metapopulation can be defined as a small population that cannot itself make a large population that is stable.Many sub populations are connected intermittently to combine and form a population.
Small population of fishes would have been separated for most of the years and are joined by when floods occur and these populations are connected by kettle ponds.
Rest of the three organism like bird, mosquito and dragon fly cannot be separated so as to form a metapopulation.
Macronutrients are a substance required in relatively large amounts by living organisms, in particular.
a type of food (e.g., fat, protein, carbohydrate) required in large amounts in the human diet.
a chemical element (e.g., potassium, magnesium, calcium) required in large amounts for plant growth and development.
a chemical element or substance required in trace amounts for the normal growth and development of living organisms.
