Biodiversity
What does biodiversity mean?
Biodiversity means the variety of living things in an area.
Name one characteristic of living things.
Living things grow. (Other answers accepted: reproduce, need energy, respond to environment)
Why do scientists classify living things?
To organize and study them more easily.
What is a vertebrate?
An animal with a backbone.
Name one threat to biodiversity.
Pollution (or habitat loss, climate change)
Name two examples of biodiversity.
Different plants and animals, such as trees and birds.
Name three characteristics of living things.
Grow, reproduce, and need energy.
How many kingdoms are there?
Five kingdoms.
What is an invertebrate?
An animal without a backbone.
How does habitat loss affect animals?
Animals lose their homes and food sources.
Why is biodiversity important?
It helps ecosystems stay healthy and balanced.
Why is reproduction important?
It allows species to survive over time.
Name three of the five kingdoms.
Animals, Plants, Fungi (others accepted)
Give two examples of vertebrates and invertebrates.
Vertebrates: fish, birds. Invertebrates: insects, worms.
Why should we protect biodiversity?
All living things depend on each other to survive.
How does biodiversity help ecosystems survive changes?
More species mean ecosystems can adapt better to changes.
Why is growth a sign of life?
Only living things grow and develop naturally.
Which kingdom do humans belong to and why?
Animal Kingdom because humans move and eat other organisms.
What role do producers play in ecosystems?
They make food using sunlight (photosynthesis).
Name two ways humans can protect biodiversity.
Reduce pollution, protect habitats, recycle, conserve energy.
What might happen if biodiversity decreases?
Ecosystems can become unstable, and species may die out.
Why is fire not considered living?
Fire does not have cells and cannot reproduce on its own.
How does classification help scientists communicate?
It gives a common system and names for living things worldwide.
What happens if one species disappears from a food web?
Other species may lose food or overpopulate, causing an imbalance.
Explain how humans can help protect biodiversity long-term.
By protecting habitats, reducing waste, and using resources responsibly.
