Microbial Roles and Climate Impact

Microbes are everywhere and play crucial roles in maintaining planetary health. They are adaptable and can help address climate change by supporting soil health, aiding in decomposition, and potentially providing biofuels. Despite their complexity, understanding and leveraging microbial diversity could be key to solving global issues like climate change and food insecurity.

What is one of the primary roles of microbes in the environment?

• Increasing greenhouse gases

• Producing fossil fuels

• Maintaining planetary chemical cycles

• Causing diseases

What percentage of microbial diversity is pathogenic to humans?

• Less than 1%

• 90%

• 10%

• 50%

What is the human microbiome?

• A type of virus

• An assemblage of microbes living in and on the human body

• A group of pathogenic bacteria

• A collection of human cells

How can mycorrhizal fungi benefit agricultural crops?

• By causing plant diseases

• By reducing plant growth

• By collecting water and nutrients for plants

• By increasing soil erosion

What is microbial decomposition?

• A way to increase greenhouse gases

• A type of biological recycling

• A process of creating new microbes

• A method of fossil fuel production

Why are researchers interested in microbial decomposition for biofuel production?

• It relies on fossil carbon sources

• It can produce sustainable biofuels

• It increases greenhouse gas emissions

• It is a slow process

How might climate change affect microbial recycling?

• It will stop microbial recycling completely

• It might speed up the process, releasing more greenhouse gases

• It will make microbes less adaptable

• It will have no effect

What characteristic makes microbes highly adaptable to climate change?

• Their reliance on fossil fuels

• Their pathogenic nature

• Their large size

• Their ability to evolve quickly

How do soil microbes contribute to carbon sequestration?

• By releasing carbon into the atmosphere

• By consuming all available carbon

• By forming biofilms that hold carbon in the soil

• By preventing plant growth

What is a potential benefit of understanding microbiome diversity?

• Reducing biodiversity

• Increasing fossil fuel dependency

• Enhancing climate change effects

• Leveraging them as part of the climate solution
