Class 6 Science Chapter 6 Case Based Questions - The Living Organisms - Characteristics and Habitats

Case 1: Terrestrial Adaptation

In a dense forest, you come across a unique animal species known as the "Long-Eared Jumper." These creatures have exceptionally long ears, brown skin, and sharp claws. You observe that they are very active during the night. Explain the adaptations of the "Long-Eared Jumper" to its terrestrial habitat.

Q1: What are the physical characteristics of the "Long-Eared Jumper" that help it survive in a forest habitat?
Ans: The "Long-Eared Jumper" has long ears, brown skin, and sharp claws. The long ears could be used for improved hearing during nighttime activities. The brown skin helps it blend with the forest environment. Sharp claws may aid in climbing trees or catching prey.

Q2: How do the behaviors of the "Long-Eared Jumper" reflect its adaptation to a forest habitat?
Ans: The nocturnal behavior of the "Long-Eared Jumper" suggests that it is adapted to the forest's low-light conditions. This adaptation helps it avoid predators and efficiently hunt for food during the night.

Q3: What is the primary function of the long ears in the "Long-Eared Jumper"?
(a) Enhanced camouflage
(b) Improved hearing
(c) Climbing trees
(d) Defense mechanism
Ans: (b) Improved hearing

Q4: Why does the "Long-Eared Jumper" prefer to be active during the night?
(a) To avoid competition with diurnal animals
(b) To conserve energy
(c) To camouflage better in the dark
(d) To enjoy cooler temperatures
Ans: (c) To camouflage better in the dark

Case 2: Desert Adaptation

In a hot and arid desert, you discover a unique plant species called the "Desert Survivor." This plant has no visible leaves and a thick, waxy stem. Explain the adaptations of the "Desert Survivor" to its desert habitat.

Q5: Describe the physical features of the "Desert Survivor" that enable it to thrive in a desert environment.
Ans: The "Desert Survivor" has no visible leaves and a thick, waxy stem. The absence of leaves reduces water loss through transpiration, while the waxy stem minimizes water loss through evaporation.

Q6: How does the "Desert Survivor" obtain water and nutrients in the desert habitat?
Ans: The "Desert Survivor" likely has deep roots that enable it to reach underground water sources. It may also have specialized tissues to absorb water and nutrients efficiently from the arid desert soil.

Q7: What is the role of the thick, waxy stem in the "Desert Survivor" plant?
(a) Enhance photosynthesis
(b) Prevent water loss
(c) Attract pollinators
(d) Store excess nutrients
Ans: (b) Prevent water loss

Q8: Why is the absence of visible leaves an advantage for the "Desert Survivor" in a desert habitat?
(a) It helps in camouflage
(b) It reduces water loss
(c) It attracts herbivores
(d) It increases photosynthesis
Ans: (b) It reduces water loss

Case 3: Aquatic Adaptation

While exploring a freshwater lake, you come across a fish species known as the "Lake Lancer." These fish have streamlined bodies and gills. Explain the adaptations of the "Lake Lancer" to its aquatic habitat.

Q9: Describe the physical characteristics of the "Lake Lancer" that are suited for life in a freshwater lake.
Ans: The "Lake Lancer" has a streamlined body that reduces friction in water, allowing it to move freely. It also has gills to extract dissolved oxygen from the water.

Q10: How do the gills of the "Lake Lancer" contribute to its survival in a freshwater lake?
Ans: The gills of the "Lake Lancer" allow it to extract oxygen from the water, ensuring a continuous supply of oxygen for respiration, which is vital for its survival in an aquatic environment.

Q11: Why does the "Lake Lancer" have a streamlined body?
(a) To attract mates
(b) To reduce friction in water
(c) To aid in camouflage
(d) To store excess nutrients
Ans: (b) To reduce friction in water

Q12: What is the primary function of the gills in the "Lake Lancer"?
(a) Extracting nutrients from the water
(b) Storing oxygen for future use
(c) Eliminating waste products
(d) Extracting dissolved oxygen from the water
Ans: (d) Extracting dissolved oxygen from the water

Case 4: Nocturnal Adaptation

In a coastal region, you come across a unique plant species called the "Midnight Bloomer." These plants only produce flowers during the night, and their leaves are sensitive to touch, closing when touched. Explain the adaptations of the "Midnight Bloomer" to its coastal habitat.

Q13: How does the behavior of the "Midnight Bloomer" reflect its adaptation to a coastal habitat?
Ans: The fact that the "Midnight Bloomer" produces flowers only during the night suggests adaptation to the coastal habitat's cooler nighttime temperatures, possibly attracting nocturnal pollinators.

Q14: Explain the role of leaf sensitivity in the "Midnight Bloomer's" survival in its coastal habitat.
Ans: The leaf sensitivity, which causes the leaves to close when touched, may protect the plant from herbivores or strong coastal winds, contributing to its survival in the coastal environment.

Q15: Why does the "Midnight Bloomer" produce flowers primarily at night?
(a) To conserve energy
(b) To attract nocturnal pollinators
(c) To avoid herbivores
(d) To withstand coastal winds
Ans: (b) To attract nocturnal pollinators

Q16: What is the main advantage of leaf sensitivity in the "Midnight Bloomer" plant?
(a) Enhancing photosynthesis
(b) Protecting against herbivores
(c) Preventing water loss
(d) Aiding in camouflage
Ans: (b) Protecting against herbivores

Case 5: Aquatic Animal Adaptation

You are studying marine life and encounter a group of dolphins in the ocean. These dolphins have prominent blowholes on the tops of their heads. Explain the adaptation of these dolphins to their marine habitat.

Q17: Describe the physical feature of the dolphins that is related to their adaptation to the marine habitat.
Ans: The prominent blowholes on the tops of their heads are a key physical feature that allows the dolphins to breathe in air when they surface in the ocean, enabling them to stay underwater for extended periods.

Q18: How do the blowholes of the dolphins contribute to their survival in the marine habitat?
Ans: The blowholes enable the dolphins to quickly and efficiently inhale air at the surface, allowing them to stay submerged for extended periods and hunt for food in the ocean.

Q19: What is the primary function of the blowholes in dolphins?
(a) Extracting oxygen from water
(b) Regulating body temperature
(c) Aiding in echolocation
(d) Breathing air when at the surface
Ans: (d) Breathing air when at the surface

Q20: Why is the presence of blowholes essential for dolphins in their marine habitat?
(a) To communicate with other dolphins
(b) To capture prey
(c) To avoid predators
(d) To breathe when surfacing
Ans: (d) To breathe when surfacing
