Metabolism•Sum TOTAL of all life processes in the body

•Every living thing carries out metabolic activities

Respiration•Process that

releases ENERGY from food

Transport•Circulation•Movement of

materials within an organism

Nutrition •When organisms take in and use materials needed for energy and all life processes

2 types of nutrition

1.Autotrophic: produce own food

•Plants, Algae (Photosynthesis)

2. Heterotrophic:•Organisms must ingest food already made in the environment

•Animals, fungi, some unicellular organisms

Regulation

•CONTROL and coordination of life activities

•Maintains homeostasis (STABILITY)

•Involves the nervous and endocrine system

Excretion •Removal of cellular (metabolic) waste

Locomotion•Ability of an organism to move

Factors that influence metabolism

•Gender•Age

• Exercise• Diet• Drugs and alcohol

Let’s summarize…

1. Describe what your metabolism consists of.

2. Describe some factors that affect a person’s metabolism.

Review:

Which term includes all the activities required to keep an organism alive?

(1.) metabolism

(2.) growth

(3.) nutrition

(4.) excretion

An activity carried on by all living plants and animals is

(1.) reproduction

(2.) respiration

(3.) photosynthesis

(4.) transpiration

Which life process prevents the accumulation of metabolic wastes in a bald eagle?

(1.) nutrition

(2.) excretion

(3.) digestion

(4.) ingestion

Which life function provides substances that may be used by an organism for its growth and for the repair of its tissue?

(1.) nutrition

(2.) excretion

(3.) regulation

(4.) reproduction

In an organism, the coordination of the activities that maintain homeostasis in a constantly changing environment is a process known as

(1.) regulation

(2.) digestion

(3.) synthesis

(4.) respiration

The life process of transport in an organism directly involves those activities used to

(1.) release energy from food

(2.) produce cellular waste products

(3.) obtain and hydrolyze materials

(4.) absorb and distribute materials

The final result of the process of respiration in animals is the

(1.) Release of oxygen as a waste product

(2.) Use of carbon dioxide to form sugars

(3.) Transfer of chemical energy to a more usable form

(4.)Enzymatic decomposition of inorganic raw materials

Which life function is most directly involved in the control of the muscles of an earthworm that is moving from dry soil to moist soil?

(1.) Regulation

(2.)Transport

(3.) Nutrition

(4.) Excretion

The movement of an organism from one place to another is known as

(1.) Circulation

(2.) Transport

(3.) Locomotion

(4.) Synthesis

Review: Identify the life process described.1. Used to produce energy.2. Needed for a species to survive3. The breakdown of food4. Type of nutrition that requires an

organism to ingest food5. The ability to move6. The removal of metabolic wastes7. When organisms take in materials from

the environment to use

8. Type of nutrition in which an organism produces its own food

9. The movement of substances throughout an organism or cell

10. When small substances join together to make larger substances

11. The removal of undigested food12. Taking in food13. Increase in cell size or cell number.
