2. about how much of the energy contained originally in the grass is usable by the
lion?
a 10 kg
b 0.1 kg
c 1 kg
od 5 kg

The correct option is B. 0.1

Explanation:

According to the information provided in the question, a zebra eats 10 kg of grass. This zebra is then eaten up by a lion.

Researched have shown that approximately 10% of an energy transfer is made from one trophic level to another. The rest of the energy is lost.

Hence, 10 kg of grass will give :

10/100× 10

= 1% or 1 kg of energy to the zebra

The grass will give

1/100× 10

= 0.1% or 0.1 kg of energy to the lion.

sand 60

clay 10

silt 30

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
