An underground water supply has a depth of 200 m of water. Water seeps in at the rate of 4 cm / year . Water is pumped out at th

e rate of 1m / year . How long will this water supply last? To find the net water loss from an underground water supply, subtract the amount that seeps into the water sup ply from the amount removed from the water supply. How long will the water supply last if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year ?

Answer:

208 years.

Explanation:

The water supply last for 208 years if the water seeps in at the rate of 4 cm / year  and water is pumped out at the rate of 1m / year. The water supply last forever if water seeps in at the rate of 10 cm / year and is removed at the rate of 10 cm / year because the same amount of water enters the underground which can be pumped from the soil. If more water is extracted from the soil as compared to it seeps, so with the passage of time water concentration in the soil decreases and in the last it disappeared.

Answer:If the large seed plant becomes extinct the finches with larger beaks will probably die out thus reducing the finch population

2)This will happen as their source of food is gone and thus leaving them to either feed on what there not used to or die

3)im not too sure of this but this is what i think; In Darwin's finches, those that have short beaks turned out to be an adaptation that made them more suited into poking holes in the ground and feed on grubs. Also 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.
