How do earthworms enrich plant growth?

Luba_88 [7]

Answer:

They tunnel through the soil, which allows air to enter.

Explanation:

Earthworms are considered to be agriculturally friendly living organisms that hold immense importance in improving the growth and productivity of plants.

They live in the soil and feed on the debris of plants such as manure, grasses, roots and dead leaves. They extensively channel and tunnel through soils while moving that causes loosening of the soil resulting in more aeration of the soil. The more the soil aeration is, the better soil drainage is.

Studies have shown that soil containing earthworms have ten times better drainage than soils that donot have earthworms. Therefore, C is the best option.

Hope it help!

Vlad [161]

Answer:

The hours are the independent variable.
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .
The domain is 0 to 30
The range is 0 to 330

Explanation:

The hours are the independent variable and should be plotted on the x-axis .

The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis

---------------

Let +W+ = wages/wk earned

Let +h+ = hours/wk worked

The equation is:

+W+=+11h+

The domain is 0 to 30

( no hrs worked to 30 hrs worked )

The range is 0 to 330

( no wages eared to +11%2A30+=+330+ earned )
