FAQs on Trick to learn ecology graph of biomes distribution/organisms and population. Video Lecture - NEET

1. What are the major biomes and their distribution on Earth?
Ans. The major biomes on Earth include tundra, taiga, temperate deciduous forest, temperate rainforest, grassland, desert, tropical rainforest, and savanna. Their distribution is determined by various factors such as temperature, precipitation, and latitude. For example, tundra is found in the polar regions, while tropical rainforests are found near the equator.
2. How do organisms adapt to different biomes?
Ans. Organisms adapt to different biomes through various mechanisms. For instance, animals in the tundra have thick fur and fat layers to withstand the cold climate, while plants in the desert have adaptations such as succulence and long roots to conserve water. These adaptations help organisms survive and thrive in their respective biomes.
3. What factors influence the population size of organisms in different biomes?
Ans. The population size of organisms in different biomes is influenced by several factors. These include availability of resources like food and water, predation, competition, disease, and environmental conditions. For example, in a tropical rainforest biome, high levels of competition for resources can result in smaller population sizes compared to a less competitive grassland biome.
4. How do human activities impact the distribution and population of organisms in biomes?
Ans. Human activities can have a significant impact on the distribution and population of organisms in biomes. Deforestation, pollution, climate change, and habitat destruction caused by human activities can disrupt ecosystems and lead to the decline of certain species or even their extinction. This can result in imbalances in the population dynamics within biomes.
5. What are the consequences of the loss of biodiversity in biomes?
Ans. The loss of biodiversity in biomes can have severe consequences. It can disrupt ecosystem functioning, reduce ecosystem resilience, and affect the stability of populations within biomes. This can lead to the loss of ecosystem services, such as pollination and nutrient cycling, which are vital for human well-being. Additionally, the loss of biodiversity can also result in a decrease in genetic diversity, making organisms more vulnerable to diseases and other environmental challenges.
