Hey I can help! I'm taking the course right now. What is the question?
Answer:
Changes in the environment affect the food sources available for birds. For example, if a flood was to occur, there would be an abundance of fish to birds to eat. So birds with bigger beaks will be able to eat fish, to live and reproduce offspring with bigger beaks. While birds with smaller beaks will not be able to catch fish to eat, therefore decreasing the population of birds with smaller beaks.
Answer: It is permeable and water flows through it.
The unsaturated zone is also called as vedose zone. It is a zone that lies above the ground water table. It includes the subsurface layers of soil. The soil and rocks present in this region consists of pores, which allows the water from the surface of soil, being absorbed and seep underground due to the effect of gravity and hence, forms a groundwater reservoir or saturated zone.
Hence, this can be said that unsaturated zone is not filled by water because it is permeable and water flows through it.
