If an ecosystem's balance is disturbed by a volcanic eruption, what will most likely occur? A. The ecosystem will not change from its original state

B. The ecosystem will eventually become balanced again

C. The consumers in the ecosystem will begin to consume carbon dioxide

D. The consumers in the ecosystem will begin to produce more oxygen

PLS HELP

This is a poorly formatted question. B.

Explanation:

First of all, B is absolutely correct, but may not be within this context. I would answer B, but be ready to fight your teacher about it.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
