Life Cycles
What is the correct order of a butterfly’s life cycle?
Egg → Caterpillar → Pupa → Adult
What is an adaptation?
A change in an animal’s body or behavior that helps it survive in its environment.
What is one way plants and animals depend on each other?
Animals rely on plants for food and oxygen, and plants rely on animals for pollination and seed dispersal.
What is the function of webbed feet in aquatic animals?
Webbed feet help animals swim by pushing against the water.
Why do scientists observe animals in their natural habitats?
To learn how animals survive and interact with their environment.
Why do plants produce seeds?
To grow into new plants and continue the life cycle
Give an example of a physical adaptation that helps an animal survive.
A giraffe’s long neck helps it reach leaves high in trees.
How do different species in the same environment avoid competition for food?
They have different structures or behaviors for obtaining food.
How do nostrils positioned on top of an animal’s head help it survive?
They allow the animal to breathe while mostly submerged in water.
What happens to traits that help animals survive?
They get passed down to future generations through natural selection.
A gardener notices that a watermelon takes longer to grow than a cucumber. What is a possible reason?
Watermelons take longer to sprout and grow because they produce larger fruits.
Why do some animals have thick fur?
Thick fur traps heat and helps animals stay warm in cold environments.
Why do some animals have eyes and nostrils positioned high on their heads?
It allows them to see and breathe while mostly submerged in water.
Why do some plants have large leaves?
Large leaves help plants absorb more sunlight for photosynthesis.
How does studying fossils help scientists understand adaptations?
Fossils show how animals have changed over time to survive in different environments.
How does an acorn help an oak tree complete its life cycle?
The acorn contains a seed that can grow into a new oak tree.
A rabbit with white fur survives better in the snow than a brown rabbit. Over time, what will happen to the population?
More white rabbits will survive and reproduce, making white fur more common in the population
A beaver and an otter both live in rivers. A beaver has large teeth and an otter has sharp claws. How do their structures help them survive differently?
Beavers use large teeth to cut trees for shelter, while otters use sharp claws to catch prey.
How does the long tongue of a hummingbird help it survive?
It allows the hummingbird to reach nectar deep inside flowers.
If an environment changes and a species cannot adapt, what might happen to that species?
The species might become extinct.
Why do some animals go through metamorphosis?
Metamorphosis allows animals to develop structures that help them survive in different environments at different stages of life.
How does camouflage help animals survive?
Camouflage helps animals blend in with their surroundings to avoid predators or sneak up on prey
What happens to an ecosystem if a species is removed?
The ecosystem can become unbalanced, leading to changes in the populations of other species.
Why do cacti have thick stems?
Thick stems store water, helping the cactus survive in dry environments.
Why do some species, like chameleons, change color?
Changing color helps them camouflage from predators or communicate with other animals.
