Biotic Factors Bio bio(s), bio(t) (G) root life include plants, animals, fungi, microorganisms bio logy bio statistics bio graphy bio technology bio sphere bio mechanics biot ic bio feedback
Ecological methods - how do we study ecology? Observing Experimenting Modeling Models are created by humans to make predictions.
Sometimes, you must be cautious in how a model interprets data.... Imagine graphing a person's height as they age. One could predict that by the time they were age 30, they would be 22 feet tall. However, the model would need to account for the slowing of growth after adolescence.
