Carbon Dynamics in Ecosystems

Miss Catherine introduces lesson 3.1, focusing on carbon in the biodome. Students are tasked with understanding the carbon cycle, particularly how carbon moves through photosynthesis and cellular respiration. The lesson includes reading an email from Dr. Brian Worry about a biodome assignment and encourages students to reflect on the missing carbon mystery.

What materials are suggested for following along with the lesson?

• A calculator and a notebook

• A smartphone and a charger

• A pen or pencil and some paper

• A laptop and headphones

What is the main focus of the article 'Carbon in the Global Ecosystem'?

• The role of water in ecosystems

• The impact of sunlight on plant growth

• The importance of oxygen in respiration

• The movement of carbon through ecosystems

What question does Dr. Brian Worry want the student ecologists to answer?

• What happened to the carbon that used to be in the air of the biodome

• Why the temperature in the biodome is rising

• How to increase plant growth in the biodome

• How to improve water circulation in the biodome

What effect did the change in decomposer population have on the biodome?

• It caused a rise in temperature

• It increased the oxygen levels

• It decreased the carbon dioxide levels

• It led to more plant growth

What process do plants use to take in carbon dioxide and produce energy storage molecules?

• Transpiration

• Fermentation

• Photosynthesis

• Cellular respiration

In cellular respiration, what is released back into the air?

• Oxygen

• Nitrogen

• Carbon dioxide

• Hydrogen

Why are energy storage molecules important for living things in the biodome?

• They store genetic information

• They help in water absorption

• They supply energy for growth and survival

• They provide structural support

What was decreasing in the biodome, leading to the collapse?

• Water levels

• Carbon in the air and energy storage molecules

• Soil nutrients

• Sunlight exposure

What do the Eco nots need to understand to build a better biodome?

• Where the carbon went and how to track it

• The impact of temperature changes

• The water cycle in the biodome

• The role of sunlight in plant growth

What is the main mystery the students are trying to solve?

• The rise in temperature

• The increase in plant growth

• The source of water in the biodome

• The missing carbon in the biodome
