NEED HELP WITH THESE 4 QUESTIONS WILL GIVE BRAINLIST!!! 1.What were some characteristics that the finches developed to give them an advantage in surviving?

2.How do you think that the one species of finch evolved into many different species, each with its own advantages?

3. In what ways do these advantages help the finches to survive and reproduce?

4. What might have happened if the finches didn't evolve into many different species?

1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.

2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection

3.  Medium ground finches with larger beaks could take advantage of alternate food

4. three species of Darwin's tree finches have been known to inhabit Floreana  but no birds singing that song on Floreana have been heard in many years.

Explanation:

This is true. The balance of such abiotic factors as water, temperature, light and air composition are crucial to any ecosystem.

Water- all living beings, whether they are plants or animals need a definite percentage of water to live and remain healthy. Water bodies of the world have more life forms present in them than found on land.

Temperature- All plant and animals are adapted to survive  between a minimum and maximum range of temperature. Distribution of different temperatures in different zones enable a wide diversity of both plant and animal life to flourish.

Light- This is the main source of energy for organisms. Most plants use light energy and transform it into chemical energy in form of complex materials that are the lifeline of animals. Animals directly or indirectly depend on plants for life.

Chemical components.- Carbon, oxygen, hydrogen and nitrogen are elements that constitute 97% of the molecules of life. A balanced supply of the elements either from the air in atmosphere or other sources is vital to life of living beings.
