Overview

In this section, include a brief description of the allocated ecosystem. You should include the following information:

Location of the ecosystem
Description of ecosystem
Biodiversity of ecosystem (richness of life in ecosystem)

AVAILABILITY OF LIGHT SOURCE IN THE DEEP SEA.....

The deep sea is located at the Bathypelagic zone. Its at a depth of 1000 fathoms (1800 metres) or more. Natural light does not penetrate this zone. Since there is no light photosynthesis cannot take place, animals living there have to depend on another source of food.

Creatures such as:

Bristlemouth
Gulper eel
Humpback Angler-fish

Temperature of the ecosystem........

The temperature of the deep sea is around 4-8 degrees Celsius. The temperature of the sea decreases as the depth of the sea increases.

Quality of water in the ecosystem......

Firstly the water in the deep sea is

Salinity of the water in the ecosystem......

The salinity of the deep sea is remarkably constant. There are only minor differences in salinity.

Quality of the air in the ecosystem......

pH of the ecosystem......

availability of nutrients and mineral salts.......

Physical Factors

Search the Internet for information on the following physical factors in the allocated ecosystem.

Light (availability of sunlight in the ecosystem),
Temperature (temperature of the ecosystem),
Water (water quality in the ecosystem),
Salinity (freshwater or seawater found in the ecosystem).
Air (quality of air in the ecosystem),
pH of the environment (how acidic or alkaline the ecosystem is),
mineral salts (availability of nutrients and mineral salts in the ecosystem)

Classification of Living Organisms

Classify at least eight of the living organisms found in the allocated ecosystem into the categories below:

Producers
Primary Consumers
Secondary Consumers
Tertiary Consumers
Decomposers

For each of the living organism, find a picture and write a short description on the organism. You may wish to include feeding habits, region in the ecosystem where it is normally found etc.

Food Web

Create a food web using at least eight of the living organisms listed above. You may wish to use Microsoft PowerPoint to create your food web. Save your food web as a picture. Finally copy and paste your picture in this section of your wiki.
