Biosphere 2 and Energy in Ecosystems

Miss Patty introduces the final unit on matter and energy in ecosystems, focusing on Biosphere 2, an experiment to sustain life in a closed system. The video discusses the challenges faced, such as food scarcity and maintaining a balanced ecosystem. Students are tasked with investigating a similar biodome's failure, focusing on energy storage molecules and ecosystem health.

What materials are suggested for the lesson on matter and energy in ecosystems?

• A calculator and a ruler

• A piece of paper and a pencil

• A textbook and a notebook

• A laptop and headphones

What was the primary goal of Biosphere 2?

• To develop new agricultural techniques

• To see if people could live in a closed system

• To study the effects of pollution

• To create a new type of ecosystem

Which of the following biomes was NOT part of Biosphere 2?

• Tropical rainforest

• Savanna

• Arctic tundra

• Mangrove marsh

What was the role of Linda Lai in Biosphere 2?

• To oversee the mangrove marsh

• To handle the coastal fog desert

• To ensure the rainforest, savanna, and desert were functioning

• To manage the tropical ocean

What was one of the main challenges faced by the crew in Biosphere 2?

• Lack of sunlight

• Insufficient food production

• Too much rainfall

• Overpopulation

What was a significant outcome of the Biosphere 2 experiment?

• It highlighted the difficulty of replicating Earth's systems

• It demonstrated the feasibility of space colonization

• It proved that closed systems are easy to maintain

• It showed that humans can live without plants

What was a major lesson learned from Biosphere 2?

• Space travel is easy

• Humans can thrive without plants

• Closed systems are self-sustaining

• Replicating Earth's environment is challenging

What issue did the biodome similar to Biosphere 2 face?

• Excessive plant growth

• Too much sunlight exposure

• Organisms getting sick and failing to reproduce

• Overabundance of energy storage molecules

What is an energy storage molecule?

• A molecule that reflects sunlight

• A molecule that organisms use to release energy

• A molecule that absorbs sound

• A molecule that stores water

Why is it important for organisms to have energy storage molecules?

• To maintain their color

• To release energy needed for survival

• To increase their size

• To improve their vision
