FAQs on Printable Worksheet: Seasonal Selection - General Knowledge for Class 1

1. What is seasonal selection in the context of evolution?
Ans.Seasonal selection refers to the process by which certain traits become more or less common in a population based on seasonal changes in the environment. This can influence reproductive success, survival rates, and ultimately the genetic makeup of a population over time.
2. How does seasonal selection affect animal behavior?
Ans.Seasonal selection can significantly impact animal behavior, such as mating rituals, foraging strategies, and migration patterns. For example, animals may develop specific behaviors to adapt to seasonal food availability or changes in climate, enhancing their chances of survival and reproduction.
3. Can seasonal selection lead to speciation?
Ans.Yes, seasonal selection can contribute to speciation by promoting adaptations to different seasonal environments. When populations become separated by geographic or ecological barriers, differing seasonal pressures can lead to the development of distinct traits, eventually resulting in the formation of new species.
4. What are some examples of seasonal selection in plants?
Ans.Examples of seasonal selection in plants include changes in flowering times, leaf drop, and seed dispersal mechanisms. Plants may adapt their reproductive cycles to align with seasonal climate patterns, ensuring successful pollination and seed germination in optimal conditions.
5. How can climate change impact seasonal selection?
Ans.Climate change can disrupt the timing and intensity of seasonal changes, affecting the selective pressures on species. This may lead to mismatches in ecological interactions, such as between predators and prey or pollinators and plants, potentially causing declines in certain populations or shifts in community dynamics.
