Answer: c. limited food availability
Both biotic and abiotic factors are responsible for shaping the evolutionary framework of the population. Resource availability can be one of the important abiotic factor in determining the evolutionary dynamics of the population or species. Limitations in resource can result in increase in competition. According to population exclusion principle when two species compete for the same limiting resource this results in co-evolution of both the species. But the extent of evolution may vary among the species. The one which undergoes more favorable evolution will be stronger competitor and drive more resources and will be fit for survival in adverse limiting conditions.
Ok, I'm sick and tired of incorrect verified answers and Yes the verified answer here is incorrect. The correct answer is "B." and here is why:
hypoxia: a condition of oxygen depletion in water
Now know this, oxygen depletion mainly occurs when dirt and soil that have been sprayed with agriculture fertilizers are introduced or enter a body of water.
Fertilizers are actually amazing on land and they improve the soil quality immensely, but in the water they promote the growth of phytoplankton. This in itself isn't so bad, but once the fertilizers wear off the plankton die and decay, which then in turn uses more oxygen.
