Water + light + nitrogen + oxygen will always produce algae/water plants. That is natures way of keeping water clean. The easiest of the above to control is the light.

The algae will reduce both air and light causing the organisms in the pond to die.
Pond weed is a weed that grows on the bottom of ponds.
the plants at the bottom of the pond cannot photosynthesize and die as the floating plants are blocking the sunlight from reaching the plants at the bottom.the whole community of organisms there will be affected.
