Carbon and Nitrogen Cycle

This is necessary for all organisms. They both move between consumers, producers and the atmosphere in a continuous cycle. (select all that appy)

Organisms that make their own food.

An organism that consumes other plants or organisms to survive.

An important compound that makes up plants and animals (as well as almost everything else)

The carbon that is from fossilized organisms is made to form what three types of fossil fuels (select all that apply)

The two most important processes that drive the carbon oxygen cycle are

carbon dioxide + water → sugar + oxygen

(What is this the formula for?)

Which of these best describes the role of plants in the carbon-oxygen cycle?

Which arrow, or series of arrows, represent the movement of atmospheric oxygen (O2) during photosynthesis?

sugar + oxygen → carbon dioxide + water

(What is this the formula for?)

Which arrow, or series of arrows, represents the movement of atmospheric oxygen (O2) during respiration?

How are we feeling about the carbon cycle?

a process in which nitrogen and nitrogen compounds go through chemical changes. These chemical changes are important so that plants and animals can use nitrogen to sustain life as it is cycled through the environment.

Nitrogen is the most abundant gas in the atmosphere so it is easy for us to pull as much nitrogen as we need straight from the air.

According to the picture which organism is responsible for nitrogen in the atmosphere being converted to a usable form?

What does it mean for nitrogen to be fixed.

This is when nitrogen is taken from a usable form and changed back into atmospheric nitrogen.

Plants can absorb nitrates from the soil and use them to form important molecules such as

How do consumers get nitrogen?

What are two ways that nitrogen can be released back into the soil from a plant or animal (check all that apply)

What role do decomposers play in the nitrogen cycle

Many species of plants have nodes that are filled with nitrogen-fixing bacteria on their roots. The nitrogen that the bacteria "fix" is then used by the plant to build plant tissues. Where does most of the nitrogen that the bacteria use come from?

Why is the nitrogen cycle important for the survival of organisms in an ecosystem?
