Name the three principal ways in which a load may be applied to a specimen.

The force that pulls material apart is tension and the one that squashes material together is compression and shear is the action of the force in trying to cut through the material.

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.

thats not a question
