Earth is a unique planet Why Because on

Earth is a unique planet. . . Why? ?

Because on Earth there are both. . . Abiotic Forms These are non-living things such as soil, rock, water, weather, temperature AND. . .

Biotic Forms These are living things such as plants, animals, single celled organisms Co-existing on Earth

Abiotic and Biotic forms work together in establishing an ecosystem Make a copy of the above chart in your notebook on the next clear page. - Thanks

When you get living things working with non-living things to create a habitat - exchanges take place between the two. A common example of this is when an animal digest foods it creates gases. These enter the atmosphere: nitrogen, carbon dioxide, oxygen, methane, and hydrogen sulfide.

This interaction between the biotic and the abiotic create different cycles. ·Carbon Cycle ·Nitrogen Cycle ·Water Cycle ·Energy Cycle

First Cycle: Carbon Cycle Copy this in your notebook Note the direction of the arrows

Draw a line between the questions & the correct answer. 1. How is carbon found in the atmosphere? 2. What role do humans & animals play in cycle? 3. What role do plants play in the cycle? 4. How is carbon found in our lithosphere (land)? 5. What contributes to carbon deposits? A. Exhaling carbon dioxide into the atmosphere & consume Carbohydrates (sugars made by producers in the act of photosynthesis) B. Carbon Deposits are fossil fuels – which are once living organisms that have been buried – burying their carbon with them. C. Organisms die, get buried & their bodies contain carbon which overtime become coal & oil – fossil fuels D. Carbon is found as a gas in the air as a chemical Carbon Dioxide which comes from the exhaust of cars, act of animals breathing and industrial smokes. E. Remove Carbon Dioxide from atmosphere by absorbing it & generate carbohydrates (sugars) in the act of photosynthesis

In your notebook, write a paragraph explaining these parts of the Carbon Cycle: Atmosphere a. IR Lithosphere l. AND

Second Cycle: Nitrogen Cycle Copy this in your notebook Note the direction of the arrows

Draw a line between the questions & the correct answer. 1. What brings the nitrogen to the ground? 2. How do animals get their needed nitrogen? 3. What joins oxygen & nitrogen to make it a solid usable form for plants? 4. How is nitrogen put back into the atmosphere? 5. What gas dominates the atmosphere? A. Special bacteria “fixing” organisms help join oxygen and nitrogen – so plants can easily use the nitrogen to make food for other organisms. B. The plentiful amount of nitrogen in the air gets attached to falling rain or lightning strikes and is deposited into the ground. C. There is 78% Nitrogen gas in our atmosphere. D. Bacteria work to release Nitrogen from Nitrites and Nitrites – some of this released Nitrogen is returned to the atmosphere. E. Eating certain plants provide animals with their needed nitrogen – which is then used to make proteins,

In your notebook, write a paragraph explaining these parts of the Nitrogen Cycle

Third Cycle: Energy Cycle Copy this in your notebook

Click on this website address look for this video introduction. Watch the video: https: //www. youtube. com/watch? v=ln. AK ICt. JIA 4 :

What do producers add to the ecosystem? How role does the soil matter play in the ecosystem? What do consumers add to the ecosystem? What do decomposer add to the ecosystem?

Third cycle: Water

What happens to allow clouds to form? How is water removed from the ocean? How does water return to Earth? What is it called when trees sweat? How does water get into the soil?

Discuss the Water Cycle

Now for a review. . . And how do the cycles relate to one another?

Function of each in cycle: Nitrogen Carbon Cycle Lithosphere Bacteria in Soil "fix" the nitrogen in soil. Decayed matter Storage space create fossil for lakes, fuels - carbons. rivers, etc. Fossil fuels store energy. Atmosphere Lightning makes nitrogen gas into usable solid. Through respiration Carbon dioxide gas is created Insulator to hold in sun's energy. Producers (Plants) Plants bring nitrogen up through roots to form proteins. Through Absorb water in Convert sun's Photosynthesis photosynthesis energy into - carbon dioxide to make sugars. sugar. become sugar. Consumers (Animals) Animals get nitrogen from plants to form proteins. Consuming producers we change sugars into energy and CO 2 Decomposers (Scavengers) Convert dead tissues back into chemical parts - nitrogen goes back to soil Water Cycle Transport location for water movement. Consume water to cleanse body systems & releases "used" water. Energy Cycle Use energy converted by plants to power activities.
