Respuesta :
The answer is D, The prey population will decrease in size
If the population size of a predator increases the prey population will decreases in size.
What is Predator-Prey relationship?
Predator-Prey relation refers to the interaction between two species where former is hunting the latter for food.
Example- Lion-Zebra, Bear-Salmon
Predator and Prey respond dynamically to one another. Higher the number of prey it will help to support the higher number of predators.
The key aspect of Predator- Prey relationship is the direct effect the predation has on numbers of their prey.
Predator- Prey relationship depends upon
- Detection of the prey
- Pursuit and capture of the prey
- Feeding
What is Population Dynamics?
The fluctuation in the numbers of a predator species and its prey that occurs over time represent Population Dynamics.
As the prey population decreases due to predator killing, the food available is less and thus the number decline.
The process reverses when the population of predators increases putting population of prey at stake and once the population of prey decreases it eventually result into decrease in the population of the predators as their is not enough population of prey to thrive upon for predators.
Impact:
1. According to Evolution, the predator-prey relationship continues to be beneficial as both the species adapt to ensure they feed without becoming meal for another predator.
2. Maintenance of Biological Diversity of the particular ecosystem and helping to keep the ecosystem stable.
3. The balance of Predator- Prey can be disrupted due to climate change and changes such as drought, urban development, foresting and overuse of resources.
4. Predator- Prey population dynamics can be useful in indicating whether the population of a species could tax the capacity of a particular ecosystem to support their numbers.
5. The knowledge of Predator- Prey population can be used in determining the number of prevailing diseases.
Thus Predator-Prey relations plays vital role in maintaining ecosystem sustainable and balance and any shift in balance would result into disruption of the stability of the ecosystem.
