Test: Living Organisms and their Surroundings - Question 10
Why do different habitats support varying plant and animal life?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 10
Different habitats support varying plant and animal life primarily due to distinct environmental conditions. Factors such as temperature, rainfall, soil type, and sunlight exposure play a crucial role in shaping the types of organisms that can thrive in a particular habitat.
Test: Living Organisms and their Surroundings - Question 11
Which of the following is an example of a biotic component of a habitat?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 11
Plants are considered biotic components of a habitat because they are living organisms that play a crucial role in the ecosystem. They interact with other organisms, such as animals and microorganisms, and with the abiotic components of the environment to form a complex web of relationships. Plants provide oxygen, food, shelter, and other essential resources for various organisms within the habitat.
Test: Living Organisms and their Surroundings - Question 12
How do adaptations contribute to the survival of species in their respective habitats?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 12
Adaptations play a vital role in helping organisms better fit their environment, thereby increasing their chances of survival and reproduction. Through adaptations, organisms develop characteristics and behaviors that make them more suited to their specific habitat, enabling them to obtain food, find shelter, avoid predators, and reproduce successfully. Over time, these adaptations can lead to the evolution of new species that are well-adapted to their environments.
Test: Living Organisms and their Surroundings - Question 13
What do adaptations refer to in the context of living things in their habitat?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 13
Adaptations in living organisms refer to specific features and habits that help them thrive in their particular habitat. These adaptations can include physical attributes like the polar bear's thick fur for warmth or behavioral traits like a bird's migration patterns. They are essential for the survival and success of organisms in their environments.
Test: Living Organisms and their Surroundings - Question 14
How are abiotic components of a habitat defined?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 14
Abiotic components in a habitat are the non-living elements that make up the environment. These include factors such as air, water, soil, sunlight, temperature, and precipitation. While biotic components involve living organisms, abiotic components are the physical and chemical factors that influence the ecosystem and the organisms within it.
Test: Living Organisms and their Surroundings - Question 15
How do the types of living things in a habitat relate to its environment?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 15
The types of living things found in a habitat are closely tied to its environment. This interdependence is a key principle in ecology, where plants and animals have specific adaptations that help them survive in their particular habitat. For example, Asiatic wild asses thriving in the warm sandy deserts of Gujarat showcase how species evolve to suit the conditions of their environment.
Test: Living Organisms and their Surroundings - Question 16
How do sandy deserts differ from tropical rainforests in terms of their climate and vegetation?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 16
Sandy deserts are characterized by hot temperatures, minimal precipitation, and xerophytic plants adapted to arid conditions like cacti. In contrast, tropical rainforests are humid and lush environments with diverse plant life. The unique adaptations of desert plants like cacti help them conserve water in harsh desert conditions, demonstrating the specialized nature of vegetation in these contrasting habitats.
Test: Living Organisms and their Surroundings - Question 17
How do animals in mountain regions adapt to survive at high altitudes?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 17
Animals in mountain regions adapt to high altitudes by developing thicker fur to insulate themselves from the cold and by producing more red blood cells to enhance oxygen transport in environments with lower oxygen levels. These adaptations help them thrive in the challenging mountainous terrain, showcasing the remarkable evolutionary strategies of these animals.
Test: Living Organisms and their Surroundings - Question 18
How does altitude influence temperature in mountain regions?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 18
Altitude plays a crucial role in determining temperatures in mountain regions, with temperatures decreasing as altitude increases. This phenomenon, known as the lapse rate, results in cooler conditions at higher elevations due to decreased air pressure and the expansion of air as it rises. Understanding this relationship between altitude and temperature is essential for comprehending the climatic variations in mountainous areas.
Test: Living Organisms and their Surroundings - Question 19
What are some key features of desert animals that help them survive in harsh desert environments?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 19
Desert animals have evolved remarkable adaptations to survive in harsh desert environments, including specialized mechanisms for water retention and efficient cooling strategies. These adaptations enable them to thrive in arid conditions by minimizing water loss and regulating their body temperature effectively. By understanding these adaptations, we gain insight into the incredible ways in which desert animals have evolved to conquer the challenges of their arid habitats.
Test: Living Organisms and their Surroundings - Question 20
How do animals in grasslands differ from those in rainforests in terms of adaptation?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 20
Animals in grasslands often have adaptations for traveling long distances for water, as these regions can have sparse water sources. In contrast, rainforest animals may have different adaptations, such as specialized camouflage, due to the dense vegetation in their environment. This difference in adaptation highlights how animals have evolved to thrive in distinct habitats with varying challenges and resources.
Test: Living Organisms and their Surroundings - Question 21
What is the term used to describe the Earth's rich variety of life residing in different habitats?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 21
Biodiversity refers to the variety of life forms found in different habitats on Earth. It encompasses different species, genetic diversity within species, and diversity of ecosystems. Protecting biodiversity is crucial for maintaining ecosystem stability and resilience.
Test: Living Organisms and their Surroundings - Question 22
Which of the following is an adaptation that animals in polar regions often have to survive in their habitats?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 22
Animals in polar regions often have thick fur or blubber to provide insulation and retain body heat in extremely cold environments. This adaptation helps them survive in the harsh conditions by maintaining their body temperature and conserving energy.
Test: Living Organisms and their Surroundings - Question 23
How do plants in arid environments such as deserts adapt to conserve water?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 23
Plants in arid environments like deserts often have adaptations such as succulent stems or leaves that can store water for extended periods. This helps them survive in dry conditions by having reserves to draw upon during periods of drought.
Test: Living Organisms and their Surroundings - Question 24
Which of the following is an example of a mutualistic relationship in an ecosystem?
Detailed Solution for Test: Living Organisms and their Surroundings - Question 24
A mutualistic relationship in an ecosystem is one where both species involved benefit from the interaction. An example is bees pollinating flowers for nectar. The bees receive food (nectar) while assisting in the pollination process, benefiting both the bees and the plants.
