Why are desert soils low in organic matter?

Biology
1 answer:
cluponka [151]3 years ago

There are two main theories for the lack of organic material in desert soils. Firstly, the organic life in most deserts is so sparse that it cannot produce much organic matter. Secondly when things do die and decompose in the desert the heat and sunlight often bleach nutrients out of the matter before it is decomposes enough to be absorbed into soil

In a science class students water a plant with the same amount of water each day for 28 consecutive days if the students use a t
Phantasy [73]

Answer:

The correct answer would be 0.85 liters.

It can be explained with the help of unit rate that is, when the rate is expressed as the quantity of 1 for example, 5 meter per second, 5 liters per day et cetera.

In this case, unit rate (liter per day) can be calculated by dividing the total amount of water used by total number of days.

Amount of water used in 28 days = 23.8 liters

The amount of water used in one day = \frac{23.8}{28}

It comes out to be 0.85 liters per day or 850 milliliter per day.

Svet_ta [14]

Answer:

organelles are very similar to present-day bacteria, suggesting a common ancestor.

Explanation:

Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.

Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.

So these organelles are similar to present-day bacteria showing that they have a common ancestor.
