Answer:
Because All organisms, including humans, need energy to fuel the metabolic reactions of growth, development, and reproduction. But plants can't use light energy directly for their metabolic needs. And half of there energy is light energy so it must first be converted into chemical energy through the process of photosynthesis.

Answer:
C
Step-by-step explanation:
Area of rectangle A is 2 and area of B is 18. 18 divided by 2 is 9. Therefore rectangle B is 9 times the area of rectangle A
It's 72
the measure of exterior angle of any regular polygon = 360/number of sides = 360/5 = 72°

Answer:
0.212 sq-m
Step-by-step explanation:
(refer to attached)
Volume of a cylinder is given by
V = πr² h, where 3 is the radius and h is the height
in this case, h is given as the length of the cylinder of 3 m
r is given to be (3/20)m
hence,
V = πr² h
V = π(3/20)² (3)
V = π (9/400) (3)
V = π (27/400) (assuming π = 3.142)
V = 3.142 (27/400) = 0.212 sq-m
