Document Summary
Chapter 1 properties of life: organization flow of energy internal constancy reproduction it evolves. The producers extract nutrients and energy from the nonliving environment and transform it into usable energy for consumers, who obtain energy and other nutrients by eating other organisms. The decomposers then obtain nutrients from dead organisms and organic wastes. All energy is not transferred from organism to organism. That reflects the second law of energy (things go from being organized to scattered as energy is transferred). Ectotherms: temperature is dependent on its surroundings (frog) Advantages: save energy, don"t have to stay warm. Advantages: span a wider area in which they can live and survive. Homeostasis: a state of equilibrium/ stabilization ph: very important to maintaining equilibrium in the body. Sexual: split dna in half into special cells from two individuals; result is a unique, non-identical offspring (humans) Problem: mutation in the parent"s cells = mutation in the offspring.
