Test 2 Review (Unit E&H)

How is it possible for energy to leave an ecosystem?

How can the soil pool move carbon into the atmosphere?

What process converts inorganic carbon into organic carbon?

Why do fossil fuels rich in chemical energy?

When does the amount of carbon dioxide in the atmosphere decrease?

Carbon atoms and other matter CANNOT be recycled in an ecosystem.

Foxes are omnivores. A species of berry that is poisonous to the fox invades. Explain what is happening using the graph.

What process converts organic carbon into inorganic carbon?

Human-driven combustion of fossil fuels accounts for the increase of CO₂ in our atmosphere.

Fossil fuels can burn because they contain C-H and/or C-C bonds.

Energy CANNOT be recycled in an ecosystem.

How does energy flow in an ecosystem?

What is carrying capacity?

Why does CO₂ decrease during the summer and early fall?

Which colored line represents the carrying capacity of this fish population?

When is the photosynthesis flux the HIGHEST?

Why is biodiversity and genetic variation important?

The cellular respiration flux is relatively stable (stays the same) throughout the year.

Every C atom in an herbivore comes from the plants they eat. Why don't all C atoms from herbivores go to carnivores?

What process moves chemical energy around an ecosystem?

Why does the energy pyramid have this shape?

Why is global temperature increasing?

Why does organic carbon contain chemical energy?

What process moves chemical energy into soil pool?

Is the soil pool organic or inorganic carbon?

Why do we care that CO₂ is increasing?

Populations experience exponential growth when...

Water contracts when it is heated up.

The Keeling Curve shows CO₂ has been increasing.

What is biodiversity?
