Practice 1.2 Systems and models 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 the concept of feedback in systems, distinguishing between positive and negative feedback.

Identify one transfer and one transformation process shown in Figure 1.
Outline how urbanization could impact two of the storages in Figure 1.
Runoff from agricultural land may lead to excess nutrients entering water bodies. Outline one indirect measure of organic pollution.
Runoff from agricultural land can result in excess nutrients entering water bodies. State one management strategy that could control the release of agricultural runoff.
Study the graph below showing a population growth model:
Identify the type of growth model shown.
Explain one limitation of this model in representing real-world population growth.

Identify two inputs to these storages.
The soil system includes storages of inorganic nutrients.
Identify two outputs from these storages.
Solid domestic waste may contain non-biodegradable material and toxins that have the potential to reduce the fertility of soils.
Explain how strategies for the management of this waste may help to preserve soil fertility.
The provision of food resources and assimilation of wastes are two key factors of the environment that determine its carrying capacity for a given species.
