Warm Up #2 Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks. Identify the following using the above scenario: Control Group: Independent variable: Dependent variable:

Life in the Earth System

What are systems? Humans strive to understand the world We organize information and identify patterns Systems thinking examines links and interactions between components to understand how it works overall System: a set of interacting components that work together

System Organization Systems can range in size and complexity The more complex systems = the more levels of organization How do your interactions with nonliving systems affect your environment?

System Biology Systems biology studies biological systems as a whole. Allows scientists to consider phenomena on different scales.

The Earth System The earth is organized into four systems Geosphere Biosphere Hydrosphere Atmosphere

Organization in the Biosphere

Components of the Biosphere Biotic: living things Abiotic: nonliving things

Identifying Biotic vs. Abiotic

Let’s take a look at some living things….

Characteristics of Living Things What characteristics do you think all organisms must have to be defined as living?

Characteristics of Living Things Made up of cells Require energy Grow and change Reproduce Respond to changes in their environment Adapt Stimuli Homeostasis
