1. which of the following processes changes complex molecules into simple molecules?

(1) excretion (3) digestion
(2) ingestion (4) egestion

6. Nutrition is the life activity by which organisms obtain and process food.
7. The endocrine and nervous systems are responsible for the life activity of regulation.
8. Taking in food from the environment is called ingestion.
9. Circulation and absorption are both parts of the life process called transport.
10. All the life processes together are its metabolism.
11. Autotrophs are organisms that can make their own food.
12. Respiration is the series of chemical reactions that releases energy.
13. The removal of cellular wastes is excretion.
14. Nutrients are the useful parts of food.
15. A stimulus is defined as a change in the environment.
16. Living things produce complex substances from simple substances by synthesis.
17. Digestion is the process that changes food into a form that can be used by the cell.
18. An increase in size and/or number of cells of an organism is growth.
19. The life process that is not necessary for the life of a single organism is reproduction.
20. Control and coordination of life activities is carried on by the nervous system.
