Exploring Environmental Challenges

Why is biodiversity important for ecosystem stability?

• Biodiversity decreases competition among species.

• Biodiversity is important for ecosystem stability because it enhances resilience and ensures essential ecological functions are maintained.

• Biodiversity leads to more predictable weather patterns.

• Biodiversity reduces the availability of resources.

How does biodiversity contribute to human health and well-being?

• Biodiversity contributes to human health and well-being by providing ecosystem services, enhancing food security, offering medicinal resources, and promoting mental and physical health.

• Biodiversity has no impact on mental health or well-being.

• Biodiversity only benefits wildlife and not humans.

• Biodiversity decreases food variety and increases health risks.

What are the primary causes of non-renewable resource depletion?

• Government regulations

• Technological advancements

• Over-extraction, industrialization, population growth, and unsustainable consumption.

• Renewable energy adoption

How does population growth contribute to the depletion of non-renewable resources?

• Population growth has no impact on resource consumption.

• Population growth contributes to the depletion of non-renewable resources by increasing demand and consumption rates.

• Population growth leads to an increase in renewable resources.

• Population growth decreases the need for energy resources.

What are the ecological effects of species extinction on food webs?

• Species extinction disrupts food webs, causing imbalances and cascading ecological effects.

• Species extinction only affects the species that are directly related.

• Food webs become more stable after species extinction.

• Species extinction has no impact on food webs.

How does species extinction impact human economies and livelihoods?

• Species extinction primarily benefits human economies by reducing competition.

• Species extinction leads to increased biodiversity and resource availability.

• Species extinction negatively impacts human economies and livelihoods by disrupting ecosystems, reducing resources, and increasing economic vulnerability.

• Species extinction has no effect on human economies.

What characteristics define invasive species?

• Invasive species are always native organisms that help ecosystems thrive.

• Invasive species are organisms that do not reproduce and are always beneficial.

• Invasive species are non-native organisms that spread rapidly, outcompete native species, and disrupt ecosystems.

• Invasive species are local plants that grow slowly and coexist peacefully with other species.

How do invasive species disrupt local ecosystems?

• Invasive species have no impact on local ecosystems.

• Invasive species enhance biodiversity by supporting native species.

• Invasive species disrupt local ecosystems by outcompeting native species, altering habitats, and introducing diseases.

• Invasive species only affect aquatic environments.

What are some strategies for the sustainable use of renewable resources?

• Ignoring community input in resource management

• Overusing resources without regulation

• Implementing efficient resource management practices, promoting conservation and restoration of ecosystems, utilizing technology for improved resource efficiency, encouraging community involvement and education, adopting policies that support sustainable practices

• Focusing solely on profit without sustainability

How can conservation efforts help protect biodiversity?

• Conservation efforts focus solely on urban development.

• Conservation efforts lead to the extinction of certain species.

• Conservation efforts protect biodiversity by preserving habitats and species, promoting sustainable practices, and restoring ecosystems.

• Conservation efforts increase pollution levels in ecosystems.
