FAQs on Biotic and Abiotic Factors Video Lecture - Crash Course for BMAT

1. What are biotic factors?
Ans. Biotic factors refer to the living components of an ecosystem, including plants, animals, fungi, bacteria, and other microorganisms. These factors interact with each other and their environment, influencing the overall balance and functioning of the ecosystem.
2. What are abiotic factors?
Ans. Abiotic factors are the non-living components of an ecosystem that influence the living organisms within it. These factors include temperature, sunlight, water availability, soil composition, air quality, and other physical and chemical factors. They play a crucial role in determining the distribution and abundance of organisms in an ecosystem.
3. How do biotic and abiotic factors interact in an ecosystem?
Ans. Biotic and abiotic factors are interconnected and interact with each other in an ecosystem. Biotic factors depend on abiotic factors for their survival, reproduction, and overall well-being. For example, plants require sunlight, water, and nutrients (abiotic factors) to carry out photosynthesis and grow, while herbivores depend on these plants for food. The presence or absence of certain biotic factors can also impact the abiotic factors in an ecosystem, such as the role of plants in influencing soil composition and moisture retention.
4. How do biotic and abiotic factors affect the population size of organisms?
Ans. Biotic and abiotic factors have a significant impact on the population size of organisms. Biotic factors such as predation, competition for resources, and disease can regulate the population size by affecting birth rates, death rates, and migration patterns. Abiotic factors such as temperature, water availability, and nutrient availability can also limit the population size by influencing the availability of suitable habitats and resources.
5. Can changes in abiotic factors lead to the extinction of species?
Ans. Yes, changes in abiotic factors can lead to the extinction of species. Rapid and drastic changes in abiotic factors, such as extreme temperature fluctuations or habitat destruction due to human activities, can make an environment unsuitable for certain species to survive and reproduce. These changes may result in the decline and eventual extinction of species that are unable to adapt or find suitable alternative habitats.
