Diversity in Living Organisms Questions
What is the primary habitat of freshwater protozoa?
-
Lakes and ponds
-
Rivers and streams
-
Wetlands and marshes
-
All of the above
D
Correct answer
Explanation
Freshwater protozoa are found in a variety of freshwater habitats, including lakes, ponds, rivers, streams, wetlands, and marshes. They can be abundant in both lentic (still water) and lotic (flowing water) environments.
Which of the following freshwater protozoa is known for its ability to form temporary feeding structures called food cups?
-
Euglena
-
Amoeba
-
Paramecium
-
Vorticella
D
Correct answer
Explanation
Vorticella is a freshwater protozoan that forms temporary feeding structures called food cups. These food cups are created by the fusion of several cilia, which form a funnel-shaped structure that helps the protozoa capture and ingest food particles.
What is the role of symbiotic algae in corals?
-
They provide corals with food
-
They help corals build their skeletons
-
They protect corals from predators
-
They give corals their color
D
Correct answer
Explanation
Symbiotic algae, known as zooxanthellae, live in the tissues of corals and provide them with food through photosynthesis. They also give corals their color, as the algae contain pigments that absorb and reflect light.
How do desert animals adapt to the scarcity of water?
-
They have long, thin bodies to reduce surface area and water loss.
-
They have specialized kidneys that conserve water.
-
They can store water in their bodies.
-
All of the above
D
Correct answer
Explanation
Desert animals have evolved various adaptations to cope with the scarcity of water. Long, thin bodies reduce surface area and water loss. Specialized kidneys conserve water by producing highly concentrated urine. Some animals can store water in their bodies, such as camels, which can store up to 200 liters of water in their humps.

What is the term for the behavior of animals that move from one place to another in response to seasonal changes?
-
Migration
-
Hibernation
-
Estivation
-
Torpor
A
Correct answer
Explanation
Migration is the term for the behavior of animals that move from one place to another in response to seasonal changes. This can include moving to find food, mates, or to escape extreme weather.
What is the term for the behavior of animals that enter a state of dormancy during the summer months?
-
Hibernation
-
Estivation
-
Torpor
-
Diapause
B
Correct answer
Explanation
Estivation is the term for the behavior of animals that enter a state of dormancy during the summer months. This is typically done to escape extreme heat and drought conditions. Animals that estivate may burrow underground, find shelter in cool, moist places, or reduce their activity levels.
What is the term for the behavior of animals that enter a state of dormancy during the winter months?
-
Hibernation
-
Estivation
-
Torpor
-
Diapause
A
Correct answer
Explanation
Hibernation is the term for the behavior of animals that enter a state of dormancy during the winter months. This is typically done to conserve energy and survive the winter without food. Animals that hibernate may burrow underground, find shelter in caves or trees, or reduce their activity levels.
