Reservoirs

A reservoir is a large natural or aritifical lake used

as a source of water supply.

Biotic/ Abiotc Factors

Fish (Biotic)

Plants (Biotic)

Bacteria (Biotic)

Rocks (Abitoic)

Producers

Hydroelectricity and sunlight is a producer for a reservoir

Consumers

Nitrogen Cycle

gaby_gurlll — 2015-02-26 00:36:01 UTC

The first step in the nitrogen cycle is when something eats food, for example a fish,

then the fish excretes ammonium. The next step is when the ammonium is produced

it turns into nitrites which then is absorbed by plants and turn into nitrates.

Below is an example of a nitrogen cycle.

Energy Flow in Reservoirs

gaby_gurlll — 2015-02-26 00:50:20 UTC

Energy flows in reservoirs are start by the Sun producing energy. This energy is then consumed by producers, consumers, and decomposers. The whole time that the energy is being transfered heat is being released or escaping.

Predation

gaby_gurlll — 2015-02-26 01:54:22 UTC

Predation is when one animal preys on another

animal for it own benefits. An example of predation

is when a fish eats a worm.

Parasitism

gaby_gurlll — 2015-02-26 01:56:46 UTC

Parasitism is when there is a symbiotic relationship

between two species and one species benefits at the others expense.

An example of parasitism is when a leech attaches to a fish and sucks it's blood.

Commensalism

gaby_gurlll — 2015-02-26 02:06:22 UTC

Commensalism is when their is a relationship between two species

where one species benefits and the other is neither harmed or benefits from

the relationship. An example of commensalism is when a small fish hides

in or around a plant to escape predators

Mutualism

gaby_gurlll — 2015-02-26 02:28:24 UTC

Mutualism is the relationship between two species and both species benefit

from the relationship. An example of mutualism is when a fish, usually smaller

cleans another fish. One fish is cleaned while the other eats.

Human effect on Reservoirs

gaby_gurlll — 2015-02-26 02:57:44 UTC

Humans have had a big impact on reservoirs. Because of the dams and water being used many

fish are now extinct or endagered. One of the reasons is for this is a fluxuation in temperature

which takes place becasue of the rise and fall of the water level. Abiotics in reservoirs are effected

because a lot of silt is removed from the floor bed which is where a lot of abiotics reside. An example

of biotics being effected by humans in reservoirs can be when the temperature increases in reservoirs

because of a decreased water level which then creates more algae which then restricts oxygen levels

and kills species depedent on that oxygen.
