Practise MYP Biology questions on 8 Human Interactions with Environments and review the explanations to check your understanding.
Use these questions for topic practice and to find ideas you want to revisit in your notes or lessons.
In the process of eutrophication, what is the specific biological role of decomposers in the formation of a 'dead zone'?
Why do ecosystems with higher biodiversity generally exhibit greater resilience following a disturbance?
Switching to renewable energy sources mitigates climate change primarily by reducing the __________ of the process, rather than removing carbon already in the atmosphere.
A balanced diet is essential for maintaining health because it provides the necessary resources for growth, repair, and which other process?
True or False: A renewable resource can become functionally non-renewable if its population drops below the Minimum Viable Population (MVP).
They prevent light from reaching the bottom of the lake
They utilize large amounts of dissolved oxygen while breaking down dead algae
They act as a primary food source for fish and invertebrates
They release excess nitrates and phosphates into the water

Species in biodiverse ecosystems always have faster reproductive rates
They have more species available to fill empty niches and perform essential functions
