Predation

Text Solution

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Definition of Predation**: - Predation is a biological interaction where one organism, known as the predator, hunts and consumes another organism, referred to as the prey. It is a crucial ecological process that influences population dynamics and community structure. 2. **Characteristics of Predation**: - In predation, the predator benefits from the interaction as it gains food and energy, while the prey is harmed as it is killed and consumed. - Predation can occur in various forms, including active hunting (as seen in carnivorous animals) or ambush tactics (as seen in some reptiles and insects). 3. **Example of Predation**: - A classic example of predation is when a lion (predator) hunts and catches a rabbit (prey). In this scenario, the lion relies on its hunting skills to capture the rabbit for sustenance. 4. **Ecological Importance**: - Predation plays a significant role in maintaining the balance of ecosystems. It helps control prey populations, which can prevent overgrazing and depletion of vegetation. Additionally, it can influence the evolution of both predators and prey through natural selection. 5. **Conclusion**: - In summary, predation is a vital ecological interaction that involves the hunting and consumption of one organism by another, exemplified by the relationship between lions and rabbits. ---
