Help me study for my IB ESS SL assessment on these following units: Topic $1$: Foundations of Environmental Systems and Societies This topic introduces fundamental concepts, models, and frameworks that underpin environmental systems and sustainability. $1\mathrm{.}1$ Environmental Value Systems $($EVSs$)$ Definition of EVSs and different types $($ecocentric$,$ anthropocentric, technocentric$).$ Influences on EVSs $($culture$,$ religion, economics, socio$-$political context$).$ Conflicts and debates surrounding environmental issues. $1\mathrm{.}2$ Systems and Models Systems concepts: inputs, outputs, processes, storages, and flows. Open, closed, and isolated systems. Models as simplified representations of reality, their uses and limitations$.1\mathrm{.}3$ Energy and Equilibria Energy transformations and laws of thermodynamics. Equilibria: steady$-$state and static. Resilience and tipping points in ecosystems. $1\mathrm{.}4$ Sustainability Definitions and principles of sustainability. Environmental, economic, and social sustainability. Sustainable development strategies. $1\mathrm{.}5$ Humans and Pollution Types of pollution: point source and non$-$point source. Sources and effects of pollutants. Pollution management strategies: prevention, control, and cleanup. Topic $2$: Ecosystems and Ecology This topic focuses on how ecosystems function and the interactions between organisms and their environments. $2\mathrm{.}1$ Species and Populations Definitions of species, population, habitat, and niche. Biotic and abiotic factors affecting populations. Limiting factors and carrying capacity. $2\mathrm{.}2$ Communities and Ecosystems Food chains, food webs, and trophic levels. Producers, consumers, decomposers, and energy flow in ecosystems. Ecological pyramids $($numbers$,$ biomass, productivity$).2\mathrm{.}3$ Functions of Systems and Ecosystems Photosynthesis and respiration as key processes. Energy and matter flows $($carbon and nitrogen cycles$).$ Productivity: gross and net primary productivity $($GPP and NPP$).2\mathrm{.}4$ Biomes, Zonation, and Succession Definition and characteristics of biomes. Factors influencing the distribution of biomes $($climate$,$ latitude, altitude$).$ Zonation and succession processes $($primary and secondary$).4\mathrm{.}1$ Introduction to Water Systems Distribution of water on Earth $($oceans$,$ freshwater, ice, groundwater$).$ Hydrological $($water$)$ cycle: processes like evaporation, condensation, precipitation, infiltration, and runoff. Human impacts on the water cycle $($deforestation$,$ urbanization$).$
