Proposal evaluating sustainable energy solutions to power Reykjavik University. The report examines tidal and geothermal energy as renewable options, detailing energy transformation processes, availability, costs, energy density, environmental impacts, and social implications. Geothermal energy is ultimately recommended due to its high energy density, reliability, minimal environmental impact, long-term cost-effectiveness, and compatibility with existing infrastructure. Includes diagrams, site-s...

An ESS essay discussing how different environmental value systems (ecocentric, anthropocentric, and technocentric) influence approaches to conserving species diversity. Using case studies of African elephants, the Mesoamerican Barrier Reef, and black rhinoceroses, the essay explores how values such as intrinsic worth, human utility, and technological innovation shape conservation strategies. It highlights the contrast between ecosystem preservation, sustainable human use, and technology-driven s...

Significant ideas: Ecosystems are linked together by energy and matter flows. The Sun's energy drives these flows and humans are impacting the flows of energy and matter both locally and globally.

Significant Ideas: The interactions of species with their environment results in energy and nutrients flow. Photosynthesis and respiration play a significant role in the flow of energy in communities. The feeding relationships in a system can be modeled using food chains, food webs and ecological pyramids.

IB ESS 2.1: Species & populations test with answers. Topic specific test. Significant ideas: Aspecies interacts with its abiotic and biotic environment, and its niche si described by these interactions. Populations change and respond to interactions with the environment. Al systems have a carrying capacity for a given species.
