Finch species living on the Galapagos Islands exhibit a variety of beak types that work for different foods. Finches that eat seeds and plant parts have beaks of the shorter, thicker variety while finches that eat insects and other small organisms have thin, pointed beaks. Over the last century the percentages of finch species have drastically changed on one island. At one time, Finch 4 comprised over 75% of the finch population on the island. Today, Finch 4 is virtually extinct. What conclusion can we reach about the conditions on this island?

A. There is an abundance of insects.
B. There are a greater number of plant species.
C. The insect populations have been severely limited.
D. Plants have died out and there are only insects for food.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex

answer///(c) the maximum number of organisms an environment can support for a long time; i believe this is correct, plz check luck;

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.
