Energy

What type of Energy do Organisms need to run?

​

By R Marsh, Ph.D.

a. Sun (solar energy)

b. Plants use solar energy to make​ food

c. Plants use plant food for : cellular energy = ATP (chemical energy)

d. Animals eat plants or animals ​for purpose of creating ATP ( chemical energy.)

​

Energy Sources:

Multiple Choice

Energy is...

• feeling good

• the ability to do work or cause change

• the food chain

• looking at TV until you fall asleep

Multiple Choice

Solar energy...

• comes from water

• comes from the wind blowing

• comes from the foods you eat

• comes from the sun

Type Description Example

Autotrophs or Organisms that make their own food:​ Plants

Producers

​

​

Heterotrophs or Organisms that obtain energy from the food they eat (ATP​) Animals

​Consumers

​

Types of Organisms:

Multiple Choice

What type of organism makes its own food?

• Autotroph

• Heterotroph

Multiple Choice

Which category of organism cannot make its own food?

• Autotroph

• Heterotroph

Multiple Choice

What is a lily pad?

• autotroph

• heterotroph

Multiple Choice

• Consumer
• Producer

Multiple Choice

• Consumer
• Producer

is the chemical reactions in the body's cells that change food into energy

Metabolism

Multiple Choice

What is metabolism?

• the ability to make things move or change

• a molecule that organisms get from the air or water around them and use to release energy

• the body's use of molecules for energy and growth

• the body system that takes in oxygen and releases carbon dioxide

Multiple Choice

The body's use of molecules for energy and growth

• system

• starch

• metabolism

• protein

Anabolism and catabolism are the two broad types of biochemical reactions that make up metabolism. Anabolism builds complex molecules from simpler ones, while catabolism breaks large molecules into smaller ones.

Catabolic / Anabolic

Multiple Choice

Consumers get their energy to do work from ___________ energy.

• solar energy

• chemical energy

• thermal energy

• nuclear energy

1. Cell division

2. Active transport

3. Movement

4. Making Molecules

5. Maintain homeostasis

Cells need energy for:

​

1. Adenine (Nitrogenous base)

2. Ribose (sugar)

3. 3 Phosphate Groups

Three phosphates bonded together by covalent bonds (phosphate bond)
