When a volcano erupts , a mixture of gases and particles is released into the air . The cooling influence of an individual volcano will dominate for the period immediately after the eruption but the warming impact will last much longer.
The abiotic factor that is essential for all aquatic ecosystem with the exception of hydro thermal vent is SUNLIGHT, THIS IS BECAUSE IT PROVIDES A SOURCE OF ENERGY.
Sunlight is very essential for aquatic ecosystems because it is the principal source of energy from which aquatic plants trap energy to make their food and provided mean of sustenance for themselves and other organisms in the water.
Answer:
B) Post-zygotic factors prevented successful reproduction.
Explanation:
Postzygotic factors may influence the formation of the fertile offspring.
The postzygotic barriers basically involves the formation of the hybrid organisms which do not survive past the embryonic stages i-e hybrid inviability / the hybrid creation that is unable to form the offspring i-e sterile.
So , in the given scenario option B )Post-zygotic factors prevented successful reproduction is the right answer .
A, B and C are the events that will cause an ecological disturbance.
Rationale:
A. Introduction of a new species: When a new specie is introduced, it increases the competition in ecosystem with the native species for food, water, space and shelter. This affects the reproductive success of the native species and thus the dynamics of ecosystem.
B. Climate change: Climate change is different from a simple change of weather. The best example would be of Antarctica where the ice is melting fast due to the global warming. The native species find it harder to adapt to the warm temperatures.
C. Late spring snowstorm: Spring is the season where the plants grow and animals shed their fur. When snowstorms occur in this season they harm these plants and animals that live there.
A recessive trait inheritance could be more prevalent in a population than the dominant because mutation could occur because the mating does not have a wide variation causing a lethal gene or an autosomal sex link to be easily passed on the offspring
