Test: Human Influences on Ecosystems - Year 11 MCQ

Sustainable agricultural practices aim to balance food production with environmental health, ensuring that farming can continue long-term without degrading the ecosystem.

Biodiversity increases genetic variability, which helps ecosystems adapt to changes and disturbances, thereby maintaining stability and resilience.

Industrial waste often contains harmful chemicals that can contaminate water sources, making it a significant source of water pollution in urban areas.

Non-point source pollution, such as pesticides washed off from farmland, comes from diffuse sources that are harder to trace compared to point source pollution.

Endangered species often have specific roles in their ecosystems that contribute to the overall health and balance, so their conservation supports broader biodiversity.

Conservation efforts in protected areas focus on preserving natural habitats and species to maintain biodiversity and ecosystem health.

Pollution, particularly water pollution, can reduce the availability of clean water necessary for agriculture, thereby impacting food supply.

Deforestation leads to habitat loss, which directly impacts the species that depend on those habitats, reducing biodiversity.

Implementing conservation practices helps manage and protect natural resources, ensuring they are used sustainably and remain available for future generations.

Invasive species often outcompete native species for resources, disrupting ecosystems and reducing biodiversity, making their management crucial for conservation.
