Practice 1.3 Energy and equilibria with authentic IB Environmental systems and societies (ESS - Old) exam questions for both SL and HL students. This question bank mirrors Paper 1, 2 structure, covering key topics like ecosystems, human impact, and sustainability. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of IB examiners.
Explain how the Second Law of Thermodynamics applies to energy flow in ecosystems.
Study the diagram below showing energy flow through trophic levels:
Explain why the pyramid is shaped this way.
Calculate the energy available to tertiary consumers if the producers contain 10,000 kJ of energy. Show your working.
Explain how negative feedback mechanisms contribute to maintaining steady state in ecosystems.
Outline how a positive feedback loop can impact an ecosystem.
Compare and contrast the impact of two named food production systems on climate change.
To what extent does the development of different societies impact their mitigation and adaptation strategies for climate change?
Explain the First Law of Thermodynamics and its relevance to environmental systems.
Analyze the following diagram of a simple food chain:
Identify the producer and primary consumer in this food chain.
Explain why the amount of biomass decreases at each trophic level.
Explain how feedback loops are involved in alternate stable states and the tipping points between them.
Earth’s atmospheric levels of carbon dioxide reached 400 ppm in 2016. Outline the potential impacts of high levels of greenhouse gases on human societies in different locations.
Discuss the consequences of changing global per capita meat consumption on the conservation of ecosystems and biodiversity.
Explain the concept of resilience in ecosystems and its relationship to biodiversity.
Define the term "steady state" in the context of ecosystems.
Explain how soil can be viewed as an ecosystem.
Compare and contrast the impact of humans on the carbon and nitrogen cycles.
Examine the role of humans in the destabilization of ecological systems.
