Challenges associated with lentic environments

Pollution.

It become reservoir for waste deposition.

Habitat of bacteria growth.

Organisms in them die due to lack of food resources.

It's lead to algal bloom.

Explanation:

Lentic environment is a stationary or still water, i.e water that doesn't flow but it is stationary at one place. Examples are ponds, ditches, reservoirs, lakes , pool, seep.

The major challenges of lentic environment are;

It become reservoir for waste deposition.

Habitat of bacteria growth.

Organisms in them die due to lack of food resources.

It's lead to algal bloom.

burning of wood and coal

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
