If you need to understand how food chains are connected in the ecosystem, which tool would you use? a. food chain b. phylogenetic tree c. food web d. periodic table

C food web

Explanation:

Food web is a system that interlock and interdependent food chain

C. Food Web

Explanation:

A food web is the network of interconnected food chains. It represents the branched food chains wherein one plant species serve as food for many different primary consumers and one specific primary consumer feeds on various plant species. This leads to interconnected network of food chains and is called as food web.

well schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  not be written on computer in this day and age.

don't delete this trying to

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.
