If you were a geologist, how would you determine if the core of the earth is liquid or solid?

S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid.

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.
