1. What is a significant piece of evidence that was used in the 1800s to suggest
Earth is very old?

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

i won't lie i don't know so go online and ask google thats what i do
