A. A biogeochemical cycle is a pathway for chemicals necessary for life to move through the environment.
2. Fill in the blanks: Matter cannot be created or destroyed. Water, carbon, nitrogen, and oxygen must be recycled somehow in the environment, which also ensures that we do not use up or lose these essential materials.
3. Fill in the blanks:
*Nitrogen is circulated in a biogeochemical cycle and is a necessary element in the structure of living things.
*Nitrogen, which accounts for 78 percent of the atmosphere, exists in the atmosphere in a form unusable by living organisms.
*The nitrogen cycle converts atmospheric nitrogen into a usable form for plants and animals, and then reconverts it to the atmospheric form.
4. What is an important thing to know about the recycling of carbon and oxygen?
A. Recycling of carbon and oxygen is important, and producers, consumers, and decomposers all have a role in the process.
i. plants through photosynthesis ii. animals through respiration iii. Decomposers through the breakdown of organic material
5. What natural processes make the water cycle work?
• evaporation => liquid water to a gas
• condensation => gaseous water to a liquid
• transpiration=> plant water to gaseous water
Additional Notes about Lesson 3.01: (Is there anything extra that you think is important?)
3.02: Nitrogen Cycle
Goals for the Lesson:
- Interpret a diagram of the nitrogen cycle.
- Describe the effects of the nitrogen cycle on living things.
1. Fill in the chart below:
Player in the Nitrogen cycle
It’s role in the Nitrogen cycle
Atmosphere
Form unusable by living things
Producers (plants) called legumes
Transfer nitrogen into a usable form for plants
Other Producers (plants)
Legumes leave bacteria in the soil and leave better soil
Consumers
Animals eat the food and let out waste
Decomposers
Breakdown the waste and release nitrogen back into the atmosphere
