rocks

200

Cycle in which photosynthesis and cellular respiration participate

What is the Carbon Cycle?

200

Process in which the break down of sugars in living things returns carbon to the atmosphere as CO2

What is cellular respiration?

200

Process in which liquid water changes into gas form

What is evaporation?

200

Nitrogen makes up this much of the atmosphere.

78%

200

Excessive use of fertilizers can cause eutrophication, which comes from the growth of this photosynthetic organism.

Algae/algal blooms

300

Cycle that involves transpiration

What is the Water Cycle

300

 Sources of carbon found underground that are composed of plants and animals that died millions of years ago.

What are fossil fuels?
300

Process in which water vapor (gas) changes into liquid water

What is condensation?

300

Process in which nitrogen gas from the atmosphere is converted into ammonia by bacteria that live in the soil and on the roots of plants called legumes

Nitrogen fixation

300

In lakes with eutrophication, fish die from a lack of this.

What is Oxygen?

400

Only cycle which does not pass through the atmosphere

What is the phosphorus cycle?

400

From the video we watched, it takes this long for a new forest to become a carbon sink.

10-20 years

400

Process in which water evaporates from the surface of plant leaves

What is transpiration?

400

Process in which soil bacteria convert nitrogen compounds in soil back into nitrogen gas which is released into the atmosphere

What is denitrification?

400

When bacteria growth from eutrophication becomes toxic it can form this, that makes us sick.

What is Red Tide?

500

Another name for the water cycle

What is the Hydrologic Cycle?

500

A way that humans can reduce the amount of carbon dioxide in the atmosphere.

What is using less fossil fuels, planting trees, or not tearing down trees?

500

Massive deforestation will cause this part of the water cycle to decrease.

What is transpiration?

500

Two things that nitrogen is the building blocks of for humans

What is Proteins (amino acids) and DNA?

500

Animals cannot make phosphorus and must get it from eating plants, who get phosphorus from this source.

What are eroded rocks?
