Animals 3 Flashcards
How do tails help animals communicate?
Animals like dogs use tails to express emotions or send signals.
Think of a wagging dog tail showing happiness.
What role do sense organs play in helping animals survive?
Sense organs help animals detect their environment for food, danger, and mates.
Picture a fox using its ears to hear prey underground.
Why do snakes have long, thin bodies compared to elephants?
Snakes use their slim bodies for flexibility and movement, while elephants have large bodies for strength and support.
Imagine a snake slithering and an elephant stomping.
How do birds’ feathers differ in function from a fish’s scales?
Feathers help in flight and insulation, while scales protect fish and reduce water resistance.
Visualize a bird soaring and a fish gliding underwater.
Why do some animals like hedgehogs have spikes as a body covering?
Spikes help protect them from predators.
Think of a hedgehog rolling into a ball of spikes.
Why do grazing animals thrive in grassland habitats?
Grasslands provide abundant grass for grazing and open space to detect predators.
Picture a zebra grazing with its herd in a wide-open plain.
What makes river habitats unique compared to forests?
Rivers provide a steady source of water and are home to both aquatic and semi-aquatic species.
Think of frogs and fish coexisting in a river.
How does rainfall affect the forest habitat?
Constant rainfall supports lush vegetation and a variety of species.
Visualize a dense rainforest with continuous rain.
Why do zebras graze in groups in grasslands?
Grazing in groups provides safety in numbers against predators.
Imagine a herd of zebras watching for lions together.
How do marine plants like seagrass support underwater ecosystems?
They provide oxygen, shelter, and food for marine animals.
Picture a turtle grazing on seagrass underwater.
Why do squirrels need balance when climbing trees?
Balance prevents them from falling and helps them escape predators.
Think of a squirrel skillfully leaping from branch to branch.
What human activities lead to habitat destruction?
Deforestation, pollution, urbanization, and overfishing.
Visualize bulldozers clearing a forest or oil spilling in the sea.
How does climate change threaten sea habitats?
It alters water temperatures, affecting marine life and coral reefs.
Picture coral reefs bleaching due to warmer waters.
What is the food chain, and how is it affected by habitat loss?
A food chain is the transfer of energy between species; habitat loss breaks the chain, leading to species extinction.
Imagine dominoes falling when one species disappears.
