Factors Affecting Producers/Energy Flow

100

Name 3 factors that affect how many energy storage molecules producers can make.

Amount of sunlight, carbon dioxide availability, water availability

200

What happens to energy storage molecules when there is less sunlight?

Producers cannot make as many energy storage molecules

300

What happens to energy storage molecules when there is more sunlight?

Producers can make more energy storage molecules

400

Which changes would most likely increase energy flow in a mangrove ecosystem?

An increase in decomposers, an increase in leaf litter

500

Biotic vs Abiotic Matter

100

Select whether oxygen, water, and sunlight are biotic or abiotic matter.

Abiotic Matter

200

Select whether plants, animals, and dead leaves are biotic or abiotic matter.

Biotic Matter

300

Is carbon dioxide biotic or abiotic?

Abiotic Matter

400

Define the term Abiotic 

• Abiotic refers to non-living components of an ecosystem.
• It includes factors like sunlight, temperature, and water.

500

Define the term biotic 

• Biotic refers to living components of an ecosystem.
• It includes all organisms such as plants, animals, fungi, and microorganisms.
• Biotic factors interact with abiotic factors (non-living elements) like water and soil..

Carbon

100

Where can carbon be found in an ecosystem? (Select 2)

Carbon dioxide, Energy storage molecules

200

When light is turned on in an aquarium with plants and fish, what happens to carbon dioxide?

Carbon dioxide decreases

300

How does carbon move in the ecosystem when plants are in sunlight?

Carbon is taken in from the air and used to make energy storage molecules

400

In a forest, if the number of energy storage molecules in trees and deer has increased, what has happened to the carbon in them?

Carbon has increased

500

Define the term carbon 

• It plays a crucial role in processes like photosynthesis and respiration in living organisms.

Ecosystem Cellular Respiration

100

Which groups in the jungle carry out cellular respiration?

Plants, animals, and decomposers

200

What happens to carbon in plants during photosynthesis?

Carbon is used to make energy storage molecules

300

What happens to carbon in animals during cellular respiration?

Carbon is given off to the air as carbon dioxide 

400

What is an ecosystem?

• An ecosystem is a community of living organisms interacting with their environment.

500

What does the term cellular respiration mean?

• Cellular respiration is the process by which cells convert glucose into energy.
