Which row shows whether the two natural resources are always managed sustainably?
▶️ Answer/Explanation
Ans: D
The table likely compares renewable resources (like timber) and non-renewable resources (like fossil fuels) in terms of sustainable management:
1. Timber: Can be sustainable if harvested responsibly with replanting, but often isn’t (deforestation occurs)
2. Fossil fuels: By definition non-renewable and cannot be managed sustainably as they take millions of years to form
The correct answer is D, indicating that neither resource is always managed sustainably. While timber has potential for sustainability, current practices often fall short, and fossil fuels are inherently unsustainable.
Which action will decrease the population of an endangered animal species in a habitat?
A) a ban on hunting this species
B) building homes for people in this area
C) educating people about this species
D) using captive breeding programmes to release animals of this species into the habitat
▶️ Answer/Explanation
Ans: B
Building homes for people in this area (B) would decrease the population because:
- It leads to habitat destruction, reducing living space and resources.
- Increases human-wildlife conflicts and pollution.
Why other options would increase populations:
– A: Hunting bans protect species from direct harm.
– C: Education promotes conservation efforts.
– D: Captive breeding directly boosts population numbers.
Thus, B is the only option that clearly threatens the species’ survival through habitat loss.
