Define Carbon Footprint
the total amount of greenhouse gases, like carbon dioxide and methane, emitted by our activities
Define Ecosystem
Bonus Question
a community of living organisms
Trophic levels and their significance
demonstrating how energy transfers, with producers forming the base and energy decreasing at each higher level, which shapes population dynamics and ecosystem stability
Define Ecosystem
a community of living organisms (biotic factors) interacting with each other and their non-living environment (abiotic factors) like water, soil, and sunlight, functioning together as a unit
Define Biodiversity
Bonus Question
the variety of all life on Earth
Define Biomass

what is Energy flow in ecosystems
the transfer of energy from one organism to another through food chains and webs
Define Conservation
prevention of wasteful use of a resource.
Define Cellular Respiration
the process where cells convert into energy
Define Replenishable Resource

Define Biome
a large geographic region characterized by a specific climate, which in turn determines the types of plants and animals that live there
Energy pyramid
Bonus Question
a model that illustrates how energy flows through an ecosystem, with the amount of available energy decreasing at each successive trophic level
Define the Three E’s of Sustainability
Environment, Economy, and Equity, representing the three core pillars required for true long-term sustainability. These are: Environmental (protecting natural resources), Economic (ensuring long-term profitability and efficiency), and Equity (fair distribution of resources and opportunities for all people)
