Food web

Explanation:

Food web are considered as the most complex feeding relationship because the animals, plants and other organisms are inter related to each other.

Producers are the main organisms that initiate any food chain or food web.There is an interrelated relationship of organism in food web.

The plant is eaten by multiple number of organism and then organism are eaten by higher organisms. The decomposers are present everywhere that feeds on the dead and decaying plants and animals to recycle nutrients back into the soil.

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.
