Advantage of high biodiversity (Why is it important)
How does biodiversity help provide food and natural medicines to humans?
Different plants and organisms provide food, nutrients, and resources used in medicine.
What are the three threatened-species classifications discussed in the presentation?
Correct answer
Critically Endangered, Endangered, and Vulnerable.
What is the difference between habitat loss and habitat fragmentation?
Habitat loss destroys natural living spaces, while fragmentation divides habitats into smaller, separated areas.
Why should people avoid buying products made from endangered animals?
Buying them supports demand for wildlife products and may contribute to illegal wildlife trade.
What two Philippine species are featured in the presentation's latest-updates section?
The Philippine eagle and the Tamaraw.
Explain how forests and wetlands help maintain clean air and fresh water.
Plants absorb carbon dioxide and release oxygen, while forests and wetlands help filter water.
What is the difference between Endangered and Vulnerable species according to the presentation?
Endangered species face a very high risk of extinction in the wild, while Vulnerable species face a high risk.
How can climate change and extreme weather threaten species that depend on specific habitats?
Changing temperatures and weather patterns can make habitats unsuitable faster than species can adapt or migrate.
How does planting native species help create a wildlife-friendly environment?
Native plants support local pollinators and help prevent the spread of harmful invasive species
What makes the Tamaraw different from a domestic buffalo, according to the presentation?
Correct answer
It has V-shaped horns, a much smaller frame, and a feisty personality.
How do earthworms and microorganisms contribute to healthy and fertile soil?
They break down dead plants and animals, returning nutrients to the soil.
A species faces an extremely high risk of extinction in the wild. What is its classification, and what abbreviation is used?
Critically Endangered (CR).
Why can overexploitation cause a species population to collapse?
Animals are hunted, caught, or harvested faster than their populations can naturally reproduce.
Why should people reduce pesticide use when protecting wildlife?
Pesticides can harm wildlife and build up in the food chain, affecting predators and amphibians.
On which four Philippine islands does the presentation say the Philippine eagle can be found?
Luzon, Samar, Leyte, and Mindanao.
Explain how bees, butterflies, and predators support agriculture.
Correct answer
Bees and butterflies pollinate plants, while predators help control pests that can damage crops.
The Philippine freshwater crocodile and Visayan warty pig are examples of which classification in the presentation?
Endangered (EN).
Explain how invasive species can threaten native species and change natural food webs.
Correct answer
Invasive species may compete for food and resources, introduce diseases, and disrupt relationships between organisms.
Give two ways people can protect natural habitats and explain why these actions matter.
People can support protected areas and report poaching. These actions help preserve habitats and reduce harm to wildlife.
Why is the Philippine eagle considered at risk, and what population estimate is given in the presentation?
It is listed as Critically Endangered, with an estimated 400 pairs left in the wild. Habitat loss is also discussed in the presentation as a major threat to wildlife.
Why are ecosystems with high biodiversity generally more resilient to environmental disturbances?
Correct answer
Different species perform important ecosystem functions. If some species are affected, others may help maintain those functions and support recovery.
Classify the following examples based on the presentation: Philippine eagle, dugong, and golden-crowned flying fox.
Philippine eagle Critically Endangered; dugong Vulnerable; golden-crowned flying fox Endangered.
Why can the combined effects of habitat loss, pollution, climate change, and overexploitation accelerate extinction?
These threats can weaken species and ecosystems at the same time, reduce survival and reproduction, and make ecosystems less able to recover.
A community wants to protect endangered animals. Explain how education, habitat protection, responsible consumption, and reporting illegal activities can work together.
Correct answer
Education builds awareness, habitat protection preserves places to live and reproduce, responsible consumption reduces demand for wildlife products, and reporting illegal activities helps enforce protection laws.
The presentation says the Tamaraw is found only on Mindoro and lists it as Critically Endangered. Based on the conservation strategies discussed, propose two actions that could help protect it and explain why.
Protect and restore its habitat to preserve food and shelter, and enforce wildlife laws to prevent hunting and other illegal activities.
