It includes biotic and abiotic factors. |
|
What is biotic factor means? What are some examples of biotic factor?
|
Biotic factor means living parts.
Some examples of biotic factors are: Plants Animals Other Organisms |
|
What is abiotic factor? What are some examples of abiotic factors?
|
Abiotic factor means nonliving parts. Some examples of abiotic factors are: Air
Water Temperature Light Soil |
|
True of False:
The size of soil particles affects how much waterthe soil can hold. |
True
The size of soil particles affects how much waterthe soil can hold. |
|

|
Can plants and animals use pure nitrogen gas.
|
No, plants and animals cannot use pure nitrogen gas.It must first be fixed into usable form
|
|
What is one example of fixing the nitrogen?
|
Lighting can fix nitrogen, allowing nitrogen to combine with oxygen to form NO³.
|
|
What happens after the lighting fixes the nitrogen gas?
|
NO³ enters the soil and is absorbed into plants through the roots. The plant then uses the nitrogen to form other compunds.
|
|
What happens after the N² enters the soil?
|
Some plants have special root nodules, like the soybean plant. Bacteria is the root nodules fix N², allowing ntirogen to form other compounds. The plant can now use the nitrogen.
|
|
How do animals get nitrogen?
|
