On an island, finches that fed on large, hard seeds had large beaks. Finches with small beaks fed on small, soft seeds. A drough

t changed the vegetation on the island. After this period, the number of seeds declined. The decrease in small, soft seeds was greater than the decrease in large, hard seeds. What are two ways the decrease in seed availability will affect the population of birds on the island?
The population of birds with large beaks will increase on the island.
The population of birds with small beaks will increase on the island.
The trait for large beaks will be passed on to future generations through natural selection.
The trait for small beaks will be passed on to future generations through natural selection.
The population of birds with large beaks and birds with small beaks will be equal on the island.

Answer:

The correct options are:

  • <em>The population of birds with large beaks will increase on the island.</em>
  • <em>The trait for large beaks will be passed on to future generations through natural selection.</em>

Explanation:

According to the theory of natural selection, those organisms tend to survive in an environment which are better adapted to live in an environment and which can better adapt to changes that occur in an environment.

The drought caused the small, soft seeds to decrease more in number as compared to the large, hard seeds. As a result, the birds having large beaks were better adapted to live in the environment as compared to the birds having small beaks. So the population of the large beak birds increased and they passed their characteristics to the future generations.

VARVARA [1.3K]

The liver plays an important role in the food digestion. The liver secretes bile juice which helps in the digestion of the fats. In the absence of digestion, this bile is stored in the gall bladder. The bile juice is the yellowish fluid, which aids in the digestion of fats (occurring in the small intestine) by emulsifying the fats molecules. the emulsification of these fat molecules is critical for their digestion, and absorption. Hence,  the liver secretes bile juice and acts to emulsify the fat in the lumen of the small intestine.

Rasek [7]

Natural selection would probably favor different varieties in the different islands. In other words, beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti (due to lack of food resources). Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits.
