HELP ME PLEASE Explain which part of it is the shadow zone?
Explain the different changes for the shape/direction of the waves as they enter certain layers.

The part outside the liquid outer core and where no any P waves receiving.

EXPLANATION:

As we already know that the shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake that does not receive any direct P waves.

QUESTION:

Explain the different changes for the shape/direction of the waves as they enter certain layers.

Seismic waves travel a curving path through the earth due to changes in composition, pressure, and temperature within the layers of the Earth. Seismic waves travel at different speeds through different materials. In this 2-layer model two wave fronts leave an impact at the same time but the lower layer is faster.

NOTE: See picture attached.

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.
