WHAT IS A WETLAND??

Wetlands are highly variable and dynamic. They are water bodies that consist of land. They are of different kinds like brackish or saline, inland or coastal, freshwater, seasonal or permanent , natural or man made.

POPULATION......

A population in an environment is a group of organisms of the same species. there are populations in every environment that has biotic factors.

BIOTIC FACTORS:

  1. Animals-crocodile, tortoise
  2. plants-Tidal, the wild garden
  3. decomposers

ABIOTIC FACTORS:

  1. Water
  2. stones
  3. mud

SOME OF THE WETLAND CARNIVORES.........

Carnivores are the animals that eat other organisms.

SOME OF THE WETLAND HERBIVORES...

SOME OF THE WETLAND OMNIVORES...

OMNIVORES ARE ANIMALS THAT FEED ON BOTH ANIMALS AND PLANTS

FOOD CHAINS

Food chains exist in every habitat where there are living organisms. The food chain for the wetland is;

FOOD WEBS

Food webs are the combination of 2 or more food chains of the same habitat. Food webs have more stability than food chains.

NEGATIVE IMPACTS OF HUMANS ON THE WETLAND:

Land development has resulted in wetlands being cleared or eroded. This causes the actual chemical makeup of wetlands to be altered, which results in an entire ecosystem being thrown off track. Then, there is waste dumping that pollutes the wetlands, greatly affecting the life forms that depend on it to live. Even hunting and trapping can have a negative effect when it's done too heavily. When humans use wetlands for agricultural drainage, the wetlands are also negatively affected.

POSITIVE IMPACTS OF HUMANS ON THE WETLAND:

  • Restrict the construction of dams.
  • Provide incentives for farming business to reduce the use of pesticides.
  • Establish protected wetlands areas.
  • Regulate water withdrawal for human use.
