Carbon Cycle

Front

What is the source of most of the carbon in a cypress tree with a trunk diameter of about 3.5 m in Florida?

Back

The carbon dioxide molecules the tree absorbed from the atmosphere.

Front

Where is the largest carbon reservoir located in a freshwater marsh ecosystem?

Back

The largest carbon reservoir is found in the atmosphere, water, all living things, and decaying materials because carbon is conserved through the cycling of matter.

Front

How does Carbon in the grass become part of a Tertiary consumer?

Back

The carbon ends up in the lion's food chain

Front

In respiration, what is consumed, and what is produced? Options: CO2, oxygen; CO2, energy; Oxygen, CO2; Oxygen, energy

Back

Oxygen, CO2

Front

Identify the two processes that assist carbon through ecosystems. Options: evaporation and condensation, photosynthesis and respiration, photosynthesis and evaporation, condensation and respiration

Back

photosynthesis and respiration

Front

Step one represents what process?
Options:
1. Animals are releasing energy into the environment and storing carbon.
2. Animals are decomposing and releasing carbon into the soil.
3. Animals are converting carbon dioxide from the atmosphere to oxygen.
4. Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere.

Back

Animals are breaking down organic molecules and releasing carbon dioxide into the atmosphere.

Front

How does mass and energy get conserved in carbon processes?

Back

Both energy and mass are conserved.

Front

What happened to the other 45% of the carbon dioxide not absorbed by plants and oceans since the Industrial Revolution?

Back

It has stayed in Earth's atmosphere, acting as a greenhouse gas.

Front

Identify which is MOST accurate about the carbon cycle.

Back

A finite amount of carbon exists on Earth, and it moves through living and nonliving materials through the carbon cycle.

Front

What is the ultimate outcome of interactions in coral reefs where many plants and animals eat one another, reproduce, and produce substances?

Back

the continuous transfer of matter and energy in and around the reef
