SS2 Biology Third Term: Terrestrial Habitats

Introduction

Terrestrial habitats refer to life on land. The nature of soil, rain fall and temperature are the major factors affecting the nature of terrestrial habitats

Most of these habitats are shown in on the map of West Africa indicating the vegetation

The terrestrial habitat is divided into four groups. These are:

  • Marsh
  • Rain forest
  • Savanna or Grassland
  • Arid land

Marsh Habitat

Marsh habitat is defined as a lowland habitat which is usually flooded or water-logged all the time. Naturally, grasses and shrubs grow in marsh but when trees grow there, it is called a swamp. Marsh is often regarded as a transition between the aquatic and terrestrial habitats

Formation of Marshes

Marshes occur in areas of lowlands and where drainage is poor. These areas include flood plains of rivers and river mouths with extensive deltas. Marshes may develop as a result of water overflowing its banks to accumulate on the adjoining coastal or low land area. Formation of marsh may also be enhanced with extensive rainfall which also contributes to the accumulation of water on a land surface.

The water in a lagoon may also flood the adjoining lowland, causing the formation of a marsh. Marsh can also be formed when ponds and lakes are filled up with soil from the surroundings and organics debris from [fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”][plants causing waterlogging.
