The roles of nitrifying and denitrifying bacteria in the nitrogen cycle are also elucidated, providing a holistic understanding of this essential nutrient cycle.

Amoeba Sisters Carbon and Nitrogen Cycle Worksheet Answer Key

The Amoeba Sisters Carbon and Nitrogen Cycle worksheet provides an overview of the two fundamental biogeochemical cycles that are essential for life on Earth. Understanding these cycles is crucial for comprehending the intricate interactions between living organisms and their environment.

Carbon Cycle

The carbon cycle involves the exchange of carbon between the atmosphere, oceans, land, and living organisms. Carbon dioxide (CO2) is absorbed by plants during photosynthesis, where it is converted into organic compounds used for growth and energy. Animals consume these plants, releasing CO2 back into the atmosphere through respiration.

Decomposers, such as bacteria and fungi, break down dead organisms and return carbon to the soil as organic matter.

Nitrogen Cycle

The nitrogen cycle involves the conversion of nitrogen into various forms that can be utilized by plants. Nitrogen-fixing bacteria convert atmospheric nitrogen (N2) into ammonia (NH3). Nitrifying bacteria then convert ammonia into nitrite (NO2-) and nitrate (NO3-), which can be absorbed by plants.

Denitrifying bacteria convert nitrate back into N2, completing the cycle.

Worksheet Answer Key, Amoeba sisters carbon and nitrogen cycle worksheet answer key

• Question 1:What is the first step in the carbon cycle? Answer:Carbon dioxide is absorbed by plants during photosynthesis.
