Question 1:
What does ecosystem diversity refer to?
Explanation: The correct answer is B) The variety of ecosystems in a region or on the planet. Ecosystem diversity refers to the variety of different ecosystems present in a region or on the planet. It includes different types of habitats, such as forests, grasslands, wetlands, deserts, and marine ecosystems, each with their own unique species compositions and ecological processes.
Question 2:
Which of the following is an example of ecosystem diversity?
Explanation: The correct answer is B) A city park with different types of plants. Ecosystem diversity can be observed in various contexts, including urban environments. A city park with different types of plants represents the diversity of ecosystems, as it may contain grasslands, flowerbeds, and tree-covered areas, each supporting different species and ecological processes.
Question 3:
Why is ecosystem diversity important?
Explanation: The correct answer is B) It contributes to ecosystem stability and resilience. Ecosystem diversity is essential for the stability and resilience of ecosystems. A greater variety of ecosystems means a wider range of ecological functions, species interactions, and nutrient cycling. This diversity enhances the capacity of ecosystems to withstand disturbances, adapt to environmental changes, and provide essential services, such as water purification, pollination, and climate regulation.
Question 4:
What is the primary factor influencing ecosystem diversity?
Explanation: The correct answer is A) Climate. Climate plays a significant role in shaping ecosystem diversity. Different climate conditions, such as temperature, precipitation, and seasonality, determine the types of ecosystems that can exist in a region. For example, tropical rainforests thrive in warm and wet climates, while deserts are adapted to arid and hot conditions. Climate directly affects the types of plants, animals, and ecological processes found in different ecosystems.
Question 5:
How can ecosystem diversity be preserved?
Explanation: The correct answer is D) All of the above. Preserving ecosystem diversity requires a combination of actions. Establishing protected areas and conservation programs helps safeguard habitats and species. Implementing sustainable land use practices, such as responsible agriculture and forestry, minimizes habitat destruction and degradation. Promoting environmental education and awareness enhances people's understanding of the importance of ecosystem diversity and encourages actions to protect and restore ecosystems.
