C: Finch A has a large, sturdy beak; and Finch B has a thin, sharp beak.

Explanation:

Darwin's finches provide an ideal model for explaining evolution. Darwin observed the finches in the 10 islands that together made the Galapagos island. He observed that the finches had adapted their lifestyle and mannerisms according to their surrounding environment. He particularly noticed the structural differences in finches's beaks according to their feeding style. Finches who fed on nuts and seeds had large sturdy beaks so that they could break them open. Finches feeding on worms had thin sharp beaks so that they can easily pick up worms and kill them.

C. Finch A has a large, sturdy beak; and Finch B has a thin, sharp beak.

they each offer a fresh glut of resources to the organisms that can arrive and exploit them. as individuals and new species continue to appear, they actively and passively alter the environment. competition for shared resources increases, local abiotic and biotic conditions shift, and the relative abundances of species change accordingly. the process is called ecological succession, and it is one of the earliest and most well-known concepts in ecology.
