Identify two ways in which you interact with each of the three parts of the biosphere - land, water, and air - every day.
Land: You live on land and obtain food from producers. Water: You drink water and swim in it. Air: You breathe in air to obtain oxygen.

Study Notes
Levels of Organization in Ecology
- Ecologists study six levels of organization: species, population, community, ecosystem, biome, and biosphere, arranged from smallest to largest.
Methods of Ecological Research
- Observation: Utilizes sensory perception and tools to collect data; essential for initial data gathering.
- Experimentation: Tests hypotheses either in controlled labs or natural settings, allowing for empirical validation of ecological concepts.
- Modeling: Creates simulations of objects and processes to understand relationships and predict ecological outcomes.
Daily Interactions with the Biosphere
- Land: Daily routines involve living on land and consuming food produced by plants, which derive nutrients from the soil.
- Water: Regular consumption of water is essential for survival; human bodies are primarily composed of water.
- Air: Humans inhale air to acquire oxygen for cellular respiration which releases energy from food, while exhaling carbon dioxide as a by-product.
Determining Water Safety
- To assess stream water safety, experimentation is key; testing water samples in a laboratory setting provides accurate safety evaluations.
