Energy Flow Test Review

This is a test review:

• Do your best to fill in what you can in your journal without finding the answers.

• Use the following slide to check your answers. • When you are confident with your answers, go

back through the slides and quiz your table partner.

Energy Pyramid•In your energy pyramid, label where:• most energy is found• least energy is found• Secondary consumers

are found• producers are found• primary consumers are

found• Herbivores are found• carnivores are found

• most organisms are found

• Least organisms are found

• Plants are found

• Tertiary consumers are found

• decomposers are found

Why is there a loss of energy as you move up the pyramid?

Why is there a loss of energy as you move up the pyramid?

• 90% of an organism’s energy consumption is used by that organism for its life process and released as heat. Only 10% is left for the next organisms in line

What are autotrophs?

What are autotrophs?

• Organisms that make their own food. • Plants, bacteria, algae

What are heterotrophs?

What are heterotrophs?

• Organisms that eat other organisms to meet their energy needs.

Describe the relationship between producers and consumers

Describe the relationship between producers and consumers

• Producers make food and oxygen for consumers and consumers provide water and carbon dioxide for plants

How are elements recycled on earth?

How are elements recycled on earth?

• Elements are contained within matter and matter is broken down (decomposed) and returned to earth to be used again.

Why are decomposers important? In what cycles are decomposers important?

Why are decomposers important? In what cycles are decomposers important?

• Decomposers break down dead organic matter- returning nutrients to the soil.

• Decomposers are a part of all nutrient cycles.

*What will happen to the food web is the rabbits go extinct?

What is the difference between matter cycle and energy flow

What is the difference between matter cycle and energy flow

Matter- what you start with you end with, it is reused

Energy-what you start with you do not end with

What do the arrows of a food chain represent?

What do the arrows of a food chain represent?

• Arrows show the direction of energy flow.

Why do most food chains have fewer than 5 levels?

Why do most food chains have fewer than 5 levels?

• There are fewer than five levels in a food chain because there is a decrease in energy available from one level to the next.

Describe the compost cycle. Why is it important?

• Organic wastes (table scraps, grass clippings, leaves etc) are collected and placed in a compost bin with soil. Decomposer break down the organic matter making it into nutrient rich soil (fertilizer)

• The nutrients made are used as fertilizers for new plants. People save money and less garbage is going to the landfill

What is the name and formula for food energy formed by plants?

• glucose (C6H12O6)
