ecosystem impact from runoff

oxygen depletion, also known as

hypoxia, is one result of runoff from

over-fertilized lawns or farmland.

after heavy rains, nutrient-rich

water enters the local aquatic

environment, cousing a series of

events to occur within the

ecosystem.

some events caused by

nutrient-rich runoff entering a lake

ecosystem are shown.

decomposers increase oxygen consumption

algae consume the available nutrients and

then begin to die oft.

move the sequence labels into the

blank boxes to sequence the

correct order of these events.

decomposers break down algae and increase

in number

an algal bloom occurs.

sequence labels

The sequence of event is as follows -  

1.After heavy rains, nutrient-rich water enters the local aquatic environment, causing a series of events to occur within the ecosystem.

2.An algal bloom occurs.

3.  Algae consume the available nutrients and then begin to die oft.

4.Decomposers break down algae and increase in number  

5.Decomposers increase oxygen consumption

6.Oxygen depletion, also known as hypoxia, is one result of runoff from over-fertilized lawns or farmland.

Explanation:

Whenever there is a heavy rainfall, runoff is generated from the nearby farmland and cropland. This runoff consists of essential soil nutrients from farmland which ultimately mixes with water bodies such as lake. In a standing water body such as lake, the water become nutrient enriched and the water plants grow uncontrollably thereby causing algal boom.  

Algal boom further leads to overproduction and depletion of oxygen from water body. The overly produced algae die and deteriorate the water quality. Also the depleted oxygen create problem for aquatic other plants and animal species.

Hence, the correct order is as follows -

1.After heavy rains, nutrient-rich water enters the local aquatic environment, causing a series of events to occur within the ecosystem.

2.An algal bloom occurs.

3.  Algae consume the available nutrients and then begin to die oft.

4.Decomposers break down algae and increase in number  

5.Decomposers increase oxygen consumption

6.Oxygen depletion, also known as hypoxia, is one result of runoff from over-fertilized lawns or farmland.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
