NOTE

BIOMES

A biome is a large, distinct ecological unit characterized by specific climate, vegetation, and animal life. These regions are defined by their unique set of abiotic and biotic factors. Biomes cover vast geographic areas and play a crucial role in shaping the distribution of life on Earth.

Local biotic components

1. Tropical Rainforest is characterized by a diverse flora with a multi-layered canopy.

It is rich in animal species, including various primates, birds, and insects.

2. Southern Guinea Savannah is a mix of grasslands and scattered trees. Wildlife in the biome may include herbivores like zebras and various bird species.
3. Northern Guinea Savannah is a transition zone with a mix of savannah and woodland. Wildlife may include herbivores like antelopes and predators like lions.
4. Sahel Savannah is characterized by a semi-arid region with sparse vegetation. It comprises of adapted flora and fauna, including drought-resistant plants and hardy animals like camels.

Major biomes of the World

 The following are some major biomes around the world,

1. Tropical Rainforest:

   - Climate: Warm and humid with high rainfall throughout the year.

   - Vegetation: Diverse, with dense and evergreen forests.

   - Fauna: Rich biodiversity, including various species of insects, birds, mammals, and amphibians.

2. Desert:

   - Climate: Arid with low precipitation and extreme temperature variations.

   - Vegetation: Sparse vegetation, adapted to conserve water.

   - Fauna: Adapted to arid conditions, including reptiles, mammals, and insects.

3. Temperate Deciduous Forest:

   - Climate: Moderate temperatures with distinct seasons.

   - Vegetation:  Broadleaf deciduous trees that shed leaves in winter.

   - Fauna: Squirrels, deer, bears, and a variety of bird species.

4. Taiga (Boreal Forest):

   - Climate: Cold with long winters and short, cool summers.

   - Vegetation: Coniferous trees (evergreen needle-leaved), such as spruce and pine.

   - Fauna: Moose, wolves, bears, and migratory birds.

5. Grassland (Savanna and Prairie):

   - Climate: Warm with seasonal rainfall variations.

   - Vegetation: Dominated by grasses, few trees in savannas.

   - Fauna: Grazing mammals like zebras and bison, as well as predators like lions and wolves.

6. Freshwater Biomes (Lakes and Rivers):

   - Habitats: Standing water (lakes) or flowing water (rivers).

   - Flora and Fauna: Diverse, including fish, amphibians, aquatic plants, and invertebrates.

7. Marine Biomes (Oceans):

   - Habitat: Saltwater environments.

   - Zones: Pelagic (open water), benthic (ocean floor), and intertidal (shoreline).

   - Flora and Fauna: Varied, from microscopic plankton to large marine mammals.

EVALUATION: 1. What is a biome

2. Identify the four local biotic components of a biome.
3. Identify and describe at least 5 major biomes of the world

CLASSWORK: As in evaluation

CONCLUSION: The teacher commends the students positively
