• It is used for growth.

• It is lost as heat.

• It is stored in bones.

• It is used in photosynthesis.

Where does most of Earth's available carbon come from?

• the constant process of photosynthesis

• sunlight that is transferred from the Sun to Earth

• the convection process that occurs in Earth's mantle

• dead organisms that are recycled back into the environment

Why do higher trophic levels in most ecosystems contain fewer organisms than lower trophic levels?

• Energy available for use to the highest trophic level is small

• Energy available for use to the lowest trophic level is small

• Energy available for use to the highest trophic level is large

• Energy available for use to the highest and lowest trophic levels is the same

In the East Texas food web, which statement is true about the role of decomposers?

• Decomposers, such as fungi, break down matter from dead organisms, returning nutrients to the soil.

• Decomposers, such as bacteria, consume living producers, like the cutleaf daisy.

• Decomposers, such as insects, directly consume matter from the Sun.

• Decomposers, such as birds, recycle energy from the Sun back to producers.

What role does the carbon cycle play in regulating Earth's climate?

• It ensures that carbon is evenly distributed between the atmosphere and the oceans, preventing drastic climate changes.

• It allows carbon to be stored in plants and soil, which helps to moderate global temperatures.

• It stops carbon from being released into the atmosphere, ensuring that the planet remains cool.

• It accelerates the release of carbon into the atmosphere, which helps to warm the planet.

How does deforestation impact the carbon cycle?

• It increases the amount of carbon stored in the soil.

• It reduces the number of trees that can absorb carbon dioxide.

• It enhances the growth of new plants that store carbon.

• It decreases the release of carbon from decayed plant matter.
