Final review MEE

What are the 3 things ALL PLANTS NEED.

• Soil, Water, and Oxygen
• Water, Love, and Sun light
• Sun light, Water, and Carbon Dioxide
• Water, Carbon Dioxide, and Glucose

Chapter 1 Question Why didn’t the plants and animals in the biodome have enough energy storage molecules?

• A change in the amount of carbon dioxide led to a decrease in the amount of energy storage molecules made by producers in the biodome.
• A change in the amount of sunlight led to a decrease in the amount of energy storage molecules made by producers in the biodome
• A change in the amount of water led to a decrease in the amount of energy storage molecules made by producers in the biodome
• There was no issue with the energy storage molecules in the biodome

Chapter 2 Question What caused carbon dioxide to decrease in the air (abiotic matter) of the biodome?

• The plants died due to no sun
• The humans killed to many animals
• The decomposers died
• The plants turned to much carbon dioxide into oxygen

Chapter 3 Question What happened to the carbon that used to be in the air (abiotic matter) of the biodome?

• It leaked out
• The carbon died
• It got trapped as dead matter
• It got trapped in producers

Vocab question!! What is cellular respiration?

• a type of atom (a tiny piece) that makes up molecules such as carbon dioxide and energy storage molecules
• the process by which plants and other producers use energy from sunlight to change carbon dioxide and water into oxygen and glucose (an energy storage molecule)
• an organism that needs to eat in order to get energy storage molecules (such as starch and fat)
• the chemical reaction between oxygen and glucose that release energy into cells

Why did the decomposers die?

• There wasn't enough energy storage molecules
• The Econauts forgot to feed them
• The Econauts buried them to deep and forgot to put earthworms in the biodome
• Carbon left the biodome because the producers made to much oxygen

Key Concept As organisms release energy during cellular respiration, carbon dioxide is produced from the carbon in energy storage molecules. This process moves carbon from biotic to abiotic matter.

• True
• False

According to the graph which of these 3 things decreased significantly over 3 years?

• Producers
• Decomposers
• Consumers
• Nothing decreased

Which one of these events increases the amount of carbon dioxide in the air?

• A producer going through photosynthesis
• A rock rolling down a hill
• A tree that is on fire
• Dead leaf's sitting on the ground

Key Concept As organisms release energy during photosynthesis, carbon dioxide is produced from the carbon in energy storage molecules. This process moves carbon from biotic to abiotic matter.

• True
• False
