sri prakash [email protected] Q1. Which of the following ecosystems is known for having the highest degree of species richness? $Select the correct option: A. Boreal forests B. Temperate deciduous forests C. Tropical rainforests D. Tropical deciduous forests Correct Answer: C. Tropical rainforests Explanation: Tropical rainforests in the terrestrial ecosystem and coral reefs in the marine ecosystem are known for having the highest degree of species richness due to their warm climate and consistent rainfall, which create a wide variety of niches for different species. Q2. Which of the following ecosystems is known for having the highest degree of species richness? $Select the correct option: A. Boreal forests B. Temperate deciduous forests C. Tropical rainforests D. Tropical deciduous forests Correct Answer: C. Tropical rainforests Explanation: Tropical rainforests in the terrestrial ecosystem and coral reefs in the marine ecosystem are known for having the highest degree of species richness due to their warm climate and consistent rainfall, which supports a wide variety of plant and animal life. Q3. Which of the following ecosystems is known for having the highest degree of species richness? $Select the correct option: A. Boreal forests B. Temperate deciduous forests C. Tropical rainforests D. Coral reefs Correct Answer: C. Tropical rainforests Explanation: Tropical rainforests in the terrestrial ecosystem and coral reefs in the marine ecosystem are known for having the highest degree of species richness due to their complex ecological niches, food-webs, and nutrient cycling. Q4. Consider the following statements about ecosystem diversity: 1. Ecosystem diversity refers to the variety of habitats, living organisms, and ecological processes in the natural world. 2. It includes variations in ecological niches, trophic structures, food-webs, and nutrient cycling. 3. Ecosystem diversity is only influenced by biological factors and not by physical parameters such as moisture, temperature, altitude, and precipitation. 4. Tropical rainforests and coral reefs are examples of ecosystems with the highest degree of species richness. $Which of the statements given above are correct? superkalam.com Discover your learning potential with SuperKalam sri prakash [email protected] A. 1, 2 and 3 only B. 1, 2 and 4 only C. All of the above D. None of the above Correct Answer: B. 1, 2 and 4 only Explanation: Ecosystem diversity encompasses the variations in ecosystems within a geographical location and includes different habitats, living organisms, and ecological processes. It is influenced by both biological and physical factors, such as moisture, temperature, altitude, and precipitation. Tropical rainforests and coral reefs indeed have the highest degree of species richness due to their complex ecological structures. Therefore, statements 1, 2, and 4 are correct, while statement 3 is incorrect as ecosystem diversity is influenced by physical parameters as well. Q5. Consider the following statements about Ecosystem Diversity: 1. Ecosystem diversity refers to the variations in ecosystems due to differences in moisture, temperature, altitude, and precipitation. 2. All forest ecosystems, irrespective of their type, have similar physical and biological characteristics due to the uniformity of global climatic conditions. 3. The diversity within ecosystems has developed over millions of years and is crucial for maintaining the ecological balance. 4. Coniferous trees of boreal forests can easily adapt and function like the trees in tropical deciduous forests under similar environmental conditions. $Which of the statements given above are incorrect? A. 4 only B. 1 and 3 only C. 2 and 4 only D. All of the above Correct Answer: C. 2 and 4 only Explanation: Statement 2 is incorrect because forest ecosystems, such as tropical rainforests, tropical deciduous forests, temperate deciduous forests, and boreal forests, show many variations mainly due to differences in physical factors like moisture, temperature, altitude, and precipitation. Statement 4 is also incorrect because the diversity of one ecosystem cannot be replaced by that of another, and coniferous trees of boreal forests cannot function like the trees of tropical deciduous forests and vice versa. This indicates that ecosystems have evolved with respect to their unique prevailing environmental conditions. superkalam.com Discover your learning potential with SuperKalam
