Irrigation projects have made it possible to practice agriculture in formerly arid areas. what might be the impact of this on the native plant population? a) they would out compete the crops and destroy them. b) they would not be affected as they do not need water. c) their growth could be hampered by the new conditions. d) they would grow better due to the availability of water.

Option C, Their growth could be hampered by the new conditions

Explanation:

The availability of water will definitely change the ecosystem. Since a desert plant has the ability to survive in dry areas, its internal system must have developed in a way that could allow it to live without water or in a limited supply of water. Now if ample amount of water is made available suddenly,  then desert plant may not be able to cope up with this change in ecosystem and it may die.

Option C is correct

a time line cause it goes from 685 to 978

i think that c)gold was found there

but i am not sure
