Warm-Up Earth’s magnetic field is due to the _______ 2. Name the four spheres 3. List some of the things that’s in the geosphere. Agenda Notes Chp 2-3 WS food chains Finish Poster presentation Homework Aug 25 - WS interior Sept 2 – Study for test chp 1 & 2

Chap 2-3 Earth is a system! System: an organized group of related objects that interact to create a whole Closed system: a system where energy, but not matter, is exchanged with the surroundings Open system: a system where both energy and matter are exchanged with the surroundings

Open or Closed?

Earth’s Energy Budget Energy cannot be created or destroyed. It can only be exchanged. Solar radiation (from the Sun): can be reflected, absorbed, or scattered. - Only 51% of solar radiation is absorbed by Earth

Earth’s Energy Budget

Trophic Levels Trophic level: a nourishment level in a food chain. Autotroph: able to use sunlight to make food Heterotroph: animals (both carnivores and herbivores) Higher trophic levels

Trophic Levels Energy moves through trophic levels in an ecosystem and is then replenished from the sun -Matter (nutrients) also moves through trophic levels… but it is cycled back into the ecosystem, NOT replenished
