Passing of traits from parents to offspring
A regulatory process in which an organism regulates its internal environment. Maintaining stable internal conditions by regulating water, temperature, salt, sugar, etc.

How are humans affecting interdependence of organisms?
Cutting down rainforests, which destroys the natural habitat of many organisms.
Organisms in a biological community live and interact with other organisms. Organisms are dependent on one another.
The combination of components and processes that serve a common function
Process in which organisms carry out many chemical reactions to get energy.
Physical motion, going from one place to another.

The process by which an organism absorbs "foods" to carry out life functions.
The study of
Any living thing
Maintaining constant oxygen levels in the body.
Process by which organisms make more of their own kind
