Answer:
For question 1. the answer is B. or Consumers and producers. (no image)
For question 2. the answer is A. or fire pit to oven to fireplace. (image)
Step-by-step explanation:
For question 1. the answer is B. or Consumers and producers. Unlike question 2. I did not have this on my test so I can't show you an image as proof. But as someone who recently when into a Ka-hoot (for some reason it doesn't take the original name) thinking the answer was only producer to find out it was producers AND consumers, trust me it's B.
Now for question 2 the answer is NOT C. or D. as many others will tell you. When I did the test (I do the test then double check) I had put in A. but after trying to find help all I kept getting were C's and D's even though it makes so sense since both of those ARE important to human technology. And I trusted them and got it wrong, and guess what the answer was.... yeah it was A. It was the fire pit to oven to fireplace. Don't feel too bad I got a 96% on the test, now you go get your 100.
