Why does only 10% move to the next trophic level?

1 answer:

5 0

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.

Jupiter has no _______, while Uranus, with a spin axis tiled 98 degrees, has the most extreme ones.

Kamila [148]

Answer:

The correct answer is

Option C. Season.

Explanation:

Jupiter has no seasons, while Uranus, with a spin axis tiled 98 degrees, has the most extreme ones. Tilting of planets are responsible for season. If there is very low tilting, the seasons are not present. In jupiter the tilting is very low that is 3 degree so that's why jupiter has no seasons. In earth, the seasons are present due to high tilting i. e. 23 degree.

lord [1]

The question lacks the diagram. The diagram has been attached below.

Answer:

Explanation:

Exons may be defined as the coding region of the RNA whereas introns are the non coding region of the RNA. The introns must be removed out from the RNA to makes it functional molecule.

The splicing of the given molecule results in the formation of single mRNA. The 1 splicing of the introns remove intron A whereas the second splicing results in the removal of intron B. The functional mRNA consists of the mRNA with exon 1,2 and 3.

Thus, the answer is 1.
