pl me quick!

answer:

(c) plants use oxygen to make their own food

answer:

b.

explanation:

we can use process of elimination here.   a is not correct.   animals do not make their own food.   c is not correct.   plants use carbon dioxide, not oxygen to power photosynthesis.   d is not correct.   decomposers break down dead animals.   therefore, b is correct.   plants are food for some consumers.  

speed = (change in distance) / (time for the change)

distance from top to bottom of segment c = (6 - 0) = 6 m

time from beginning to end of segment c = (14 - 4) = 10 s

speed = (6 m) / (10 s)

speed = 6 m/s
