Thinking About The Environment
1. This beach is an example of dynamic equilibrium because it is in a steady state in which the rate of change in one direction is the same as the rate of change in the opposite direction. This is an example of a negative feedback mechanism because this keeps the system in a dynamic equilibrium.
2. Because of the outdated hypothesis that the Earths organisms adjust to the environment to keep it habitable for life.
3. Biological, geological, and chemical interactions.Because it takes these materials make up the chemical compounds of cells.
4.
- carbon-protiens, carbohydrates, and other molecules essential to life contain carbon and organisms must have carbon to live.
- nitrogen-is crucial for all organisms because it is an essential part of biological molecules such as protiens and nucleic acids.
- phosphorus-when released by decomposers becomes part of the soils pool opf inorganic phosphate for plants to reuse, it moves through the food web as onr organism consumes another.
- sulfer-is an essential component of protiens in organisms
