colder temperatures and lower light levels limit the types of organisms that can live in deep lake waters
Because they do not get the sunlight that they need.
sunlight reaches the bottom
Yes they eat the weeds at the bottom of rivers, ponds and lakes. They will also eat crayfish .
Fewer organisms live at the bottom of a deep lake compared to the top due to reduced light availability for photosynthesis, lower oxygen levels, and limited nutrient availability. The lack of sunlight restricts the growth of plants and algae that form the base of the food chain, leading to less food and habitat for other organisms. Temperature differences and pressure can also make the bottom of deep lakes less hospitable.
There is no bottom of those lakes. If you're looking for the pixies, they are in the caves in the middle of the lakes.
no lakes with plants are rather coooler than without it
Water pressure increases with depth. So in a deep lake the bottom of the damn needs to be thicker to accommodate the greater water pressure.
Aquatic plants
cattail
yes
I think lakes are marine because lakes can be nasty and drity or clean and drinkable.
Lakes are different from ponds because lakes are bigger than ponds and the sunlight is able to hit the bottom of a pound and create algae. The sunlight is not able to hit the bottom of a lake.
