AQUATIC HABITAT
CONTENT
• Habitat (Aquatic habitat)
• Marine Habitat
• Horizontal and Vertical Zonation of Marine Habitats
• Distribution of Organisms and Adaptations to Marine Habitat
• Estuarine Habitat
• Freshwater Habitat
HABITAT (AQUATIC HABITAT)
Habitat is a place where organisms (plants, microorganisms and animals) are naturally found e. g. the habitat of tadpole is the bottom of fresh water ponds or streams
There are three main types of habitats, namely; aquatic habitat (in or around water), terrestrial habitat (in or on land) and arboreal habitat (in or on trees)
There are three kinds of aquatic habitat;
i. marine/salt water habitat e.g. ocean, seas
ii. brackish water habitat (where salt and fresh water mix) e.g. delta, lagoon, bay
iii. Fresh water habitat (contain little or no salt) e.g. lakes, rivers, streams.
MARINE HABITATS
Characteristics of marine habitats are as follow:
1. The marine habitats constitute the largest habitat in the biosphere (70% of the earth’s area)
2. They do… Click here to order the complete Biology Lesson Note for SS2 first term

TERRESTRIAL HABITATS
CONTENT
• Terrestrial Habitats
• Marsh
• Forest
• Grassland
• Arid land
TERRESTRIAL HABITATS
Organisms of the land are called terrestrial organisms. They include plants and animals that are found living on the ground and under the ground.
Basically, terrestrial habitat is subdivided into four main parts, namely;
i. marsh
ii. forest
iii. grassland/ savanna
iv. arid land/ desert
EVALUATION
1. What are terrestrial organisms?
2. List four types of terrestrial habitats
MARSH
Marsh is a low land, flooded in rainy season and usually waterlogged because of poor drainage. The vegetation is predominantly of grasses and shrubs. When trees grow in a marsh, it is called a swamp. Marsh is a transition between the aquatic habitat and terrestrial habitat.
FORMATION OF A MARSH
Marshes develop as a result of… Click here to order the complete first term Biology Lesson Note for SS2
