Runoff from agricultural land carries chemicals from fertilizers that collect in a lake. The buildup of chemicals can eventually cause -

river tributaries to reroute, changing the flow of natural waterways.
aquatic life, such as fish and turtles, to die from a lack of oxygen
о
excess water to fill the aquifer, resulting in pore shrinkage and subsidence.
rainfall levels to drop causing drought and a shorter growing season

sorry, but you do not have posted the diagram.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
