Biome- a regional or global land area that is characterized by the plants, animals and climate in that area

3. Examples: dry, wet, hot, cold, humid
the weather conditions prevailing in an area in general or over a long period
Examples: dry, wet, hot, cold, humid
Climate

4. Biotic factors living or once-living organisms in the ecosystem.
Examples: animals, birds, plants, fungi, and other similar organisms

5. Abiotic factors
non-living physical and chemical elements in the ecosystem
Examples: water, air, soil, sunlight, and minerals

6. he position or function of an organism in a community of plants and animals
Example: in a forest there may be a niche for an organism that can fly and eat nectar from blossoms
Niche

7. Symbiotic relationships
“I'll scratch your back if you scratch mine”
A close, prolonged association between two or more different organisms of different species that may, but does not necessarily, benefit each member
Three main types of symbiotic relationships:
Mutualism: Both organisms benefit
Commensalism: one organism benefits, the other is unaffected
Parasitism: One organism benefits, the other is harmed

8. Nitrogen is necessary for all known forms of life on Earth
Processes in the nitrogen cycle include:
Fixation: bacteria change nitrogen into ammonium
Nitrification: the process by which ammonium gets changed into nitrates by bacteria
Assimilation: This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll
Ammonification: When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle
Denitrification: Extra nitrogen in the soil gets put back out into the air
Nitrogen Cycle

9. Carbon Cycle Process above ground
Carbon is removed from the atmosphere by plants through the process known as photosynthesis
Carbon is later transferred to animals who consume, or eat plants. When plants and animals die, much of their carbon is returned to the atmosphere as the organisms decompose
Process below ground
Every so often, a plant or animal does not decompose right away. Their bodies are trapped in locations where decomposition can simply not take place
Instead of returning to the atmosphere, the carbon from these lifeforms is trapped within the Earth. Over millions of years, more and more of the carbon on Earth has been trapped in this manner
Carbon Cycle

10. Water cycle Processes include:
Evaporation: the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air
Condensation: Water vapor in the air gets cold and changes back into liquid, forming clouds
Precipitation: So much water has condensed that the air cannot hold it anymore. The clouds get heavy and water falls back to the earth in the form of rain, hail, sleet or snow
Collection: When water falls back to earth as precipitation, it may fall back in the oceans, lakes or rivers or it may end up on land. When it ends up on land, it will either soak into the earth and become part of the “ground water” that plants and animals use to drink or it may run over the soil and collect in the oceans, lakes or rivers where the cycle starts all over again
