Objective: 8.L.5.1 –Summarize how food provides the energy and molecules required for building materials, growth, and survival of all organisms.

All Living Things Share Four Characteristics of Life All living things have an ability to acquire materials and energy All living things have an ability to respond to their environment Living things are highly organized, from the smallest part to the largest All living things have an ability to reproduce

Draw this chart as large as you can on landscape orientation Draw this chart as large as you can on landscape orientation. Leave room to add material All Living Things Need energy respond to environment highly organized reproduce

All Living Things Need energy nutrients

The ability to work and work is make something against a force. What is energy? The ability to work and work is make something against a force.

What make Energy so special? Energy can be found in many things, and takes many forms. Energy can’t be created or destroyed. Energy can be transferred and transformed. Energy can travel through space. A huge amount of energy is located in the molecules that make up all matter

Why do our cells need energy?  To Survive and Thrive  To grow and develop  To carry out daily functions  To repair  To reproduce How do our cells get energy to do work?  From the energy stored in the chemical bonds of food molecules.

Is it Food?

What is Food? Food is an organic substance containing carbohydrates, proteins, and/or fats that serve as both fuel and building material for an organism

All food are Nutrients but not all Nutrients are Food What are nutrients? Substances that organisms must take in to carry out their life processes. They can be organic (contains Carbon… living) material. They can be inorganic (no carbon… non-living) material.

All food are Nutrients but not all Nutrients are Food Organisms require inorganic nutrients such as water, vitamins and minerals to grow and survive. However, they are not a source of energy nor are they used a building materials. Inorganic materials are nutrients but not food.

THE SIX ESSENTIAL NUTRIENTS

Organic Nutrients Carbohydrates Proteins organic compounds that consist of long chains of amino acids organic compounds found in living tissue Provide energy Help build and repair muscles Include sugars, starch, and cellulose.

Organic Nutrients Fats/lipids a natural oily or greasy substance occurring in animal. Also called triglycerides Helps process vitamins and minerals 2nd source of energy for cells Acts as the body's insulator protecting organs and absorbing shocks

Inorganic Nutrients Vitamins Minerals Needed for the body to work properly, for growth and development, and overall, for maintaining normal health. Plays an important role in bodily functions such as metabolism, immunity and digestion Vital for growth and development encourages chemical reactions in cells 13 essential vitamins, including vitamins A, C, D, E, and K and B vitamins such as riboflavin and folate

Inorganic Nutrients Water Water comprises about ¾ of the human mass and is a major component in every cell. Water transports nutrients, eliminates waste, serves as a catalyst for chemical reactions

SIX ESSENTIAL NUTRIENTS Water –transports nutrients, eliminates waste, serves as a catalyst for chemical reactions Vitamins –encourage chemical reactions in cells Minerals – help form our bodies structure and regulate processes Carbohydrates – provides energy for cells Proteins – helps build and repair muscle Fats – acts as the body's insulator protecting organs and absorbing shocks, helps process vitamins and minerals, and provides energy
