Tropical Rainforest & Intertidal Zone
Tropical Rainforest O is an ecosystem type that occurs roughly
within the latitudes 28 degrees north or south of the equator
O Rainforests are home to half of all the living animal and plant species on the planet
O It is likely that there may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests.
Types of Tropical Rainforest
O Lowland equatorial evergreen rain forests: These forests occur in a belt around the equator.
O Moist deciduous and semi-evergreen seasonal forests: Some trees in these forests drop some or all of their leaves during the winter dry season.
O Montane rain forests: some of which are known as cloud forests
O Flooded forests
Forest StructureO Forest floor: Only plants adapted to low light can
grow in this regionO Understory Layer: is home to a number of birds,
small mammals, insects, reptiles, and predatorsO Canopy Layer: is the primary layer of the forest
forming a roof over the two remaining layers.O Emergent Layer: contains a small number of very
large trees, called emergent
INTERTIDAL ZONEO is the area that is above water at low
tide and under water at high tideO A typical rocky shore can be divided
into a spray zone or splash zone also known as the supratidal zone
O The intertidal zone is one of a number of marine biomes or habitats, including estuaries, neritic, surface and deep zones.
ZonationO Marine biologists and others divide
the intertidal region into three zones:1. Low 2. Middle3. High
