On Isle Royale, wolves are the main predators of moose. The graph shows the changing wolf and moose populations on the island over a 50-year time span.

The graph plots the populations of moose and wolves in separate lines from 1955 to 2005. The two populations appear to follow opposite trends: when one population is higher, the other population is lower.

Which statement provides the strongest explanation for the trends in the two populations?

A. The populations of predators and prey are limited by abiotic factors only.

B. Predation acts a density-dependent limiting factor on prey, but not on predators.

C. Predation acts as a density-independent limiting factor on predators, but not on prey.

D. Predator-prey relationships act as density-dependent limiting factors on both predators and prey.

We can plant more trees and plants.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.

1) the mayans built pyramids just like the egyptians. the mayans also used hieroglyphics like them.2) power was passed down by family. for example, if the father dies, the son would be the next king.3)they both built pyramids for their structures.4)the main crop for the mayans was maize.5)they also grew manioc, beans,  squash,  amaranth, and chile peppers.

It would be the equator.
