What two characteristics do fungi lack that forced them to become decomposers?? Please help :) **25 points**
Tamiku [17]
Fungi lacks the ability to produce their own food because they do not have chloroplast which is needed to obtain energy from the sun and convert it into food. Also fungi lack ability to fix nitrogen which has to be incorporated into their food. They also can not fix carbon and utilize it to produce food. Because of these they have to depend on dead organic matters for food.

PLEASE I NEED THIS ASAP If you had a cell that was cube-shaped with a side length of 20µm, calculate the surface to volume ratio
weeeeeb [17]

Answer:

Ratio = 3\times 10^5

Explanation:

Side of a cube, a = 20 µm

a=20\times 10^{-6}\ m

The surface area of a cube, A = 6a² (a is side of the cube)

The volume of a cube, V = a³

The ratio of the surface to volume ratio of the cell will be given by :

R=\dfrac{6a^2}{a^3}\\\\R=\dfrac{6}{a}\\\\R=\dfrac{6}{20\times 10^{-6}}\\\\R=3\times 10^5

So, the ratio of the surface to volume ratio of the cell 3\times 10^5.
