Biodiversity
Explain what is biodiversity with your own words.
It is the diversity of living things in a certain place.
What is habitat destruction?
When natural habitats are damaged or removed.
What is a habitat?
The place where an organism lives.
What process allows plants to make their own food?
Photosynthesis
“Humans are part of biodiversity.”
True. We are part of the animal kingdom too.
Mention 3 types of living things that add up to the "biodiversity"
animals, plants, fungi, bacteria,...
How does pollution harm biodiversity?
It can poison organisms and damage habitats.
Which ecosystem usually has the greatest biodiversity?
Rainforest.
Why are pollinators important?
They help plants reproduce.
“If one species disappears, ecosystems stay exactly the same.”
False, the whole ecosystem is affected.
Biodiversity is important because:
It keeps ecosystems balanced and supports life on Earth.
Why is deforestation dangerous for biodiversity?
It destroys habitats and reduces resources for species.
Why can’t a polar bear survive in the desert?
It is adapted to cold environments, not hot dry climates.
What is an endangered species?
A species at risk of extinction.
“Some fungi help ecosystems by decomposing dead organisms.”
True.
What could happen if one species disappears? Give an example.
Food chains and ecosystems can be affected.
How can invasive species (taking species from one ecosystem to another) threaten biodiversity?
They compete with native species for food and space and may upset ecosystem balance.
Why do ecosystems need both living and nonliving things to function?
Living things depend on water, sunlight, air, and soil to survive and keep the ecosystem balanced. While also living things, through decomposers and food chains keep the energy flowing.
How can the extinction of one species affect an entire ecosystem?
It can disrupt food chains and relationships between species.
“An ecosystem with more biodiversity is usually more resistant and balanced".
True
How does biodiversity help humans?
It provides food, medicine, oxygen, materials, etc.
Explain how climate change can affect biodiversity in both land and ocean ecosystems.
Changing temperatures and weather patterns can destroy habitats, affect migration, melt ice, warm oceans, and make survival difficult for many species.
Why would removing trees from a forest affect more than just the animals living in trees?
Trees affect food, shelter, oxygen, soil, water cycles, and many interconnected species.
How can losing biodiversity affect humans?
Humans may lose food sources, medicine, clean air and water, and healthy ecosystems that support life.
“Top predators are unimportant because there are fewer of them.”
False.
