Ecosystem And Biomes Flashcards
……..is any part of earth that support life
Ecosystem
Two main component of ecosystem are
Biotic and abotic
Abiotic component consist of
Sunlight Water Gases in the air Ph Salinity Solid mineral materials etc
What are biotic component
They consist of living things plants and animals and certain micro organisms
Biotic fall into two groups
Autotrophs
Heterotropes
In aquatic habit the autotrophs or primary consumers are
Phytoplanktons
Two main process that tends to account for the stability and continuance of life is……
Flow of energy
Cycling of materials eg nitrogen , water, oxygen etc
………is a collection of different ecosystem that share similar climatic condition
Biome
Types of biome
Terrestrial biome
Marine biome
Terestrial biome is name after
Their plant dominant
Marine biome is name after their
Animal dominant
Biome of Nigeria can also be referred to as
Local biome
Tundra is a…….biome
terrestrial biome
The forest biome dominate the…..part of nigeria
Southern part of nigeria
Forest biome consist of
Swap forest and rain forest
Niger Delta, calabar, lagos and badagry are location where we find
Swamp forest
List two kinds of swamp forest
Mangrove swamp
Fresh water swamp
List some plant found in swamp forest
Raphia palms
Coconut
Example of rain forest trees
Sapele wood Iroko Oil palm Mahogany Obeche
………is any forest dominated by woody plants and grasses are conspicuously absent
Rain forest
Which forest is the richest in biodiveristy
Rain forest
…….is the richest of all biome where neither shortage of water not extreme temperature limits growth of plant during any period of time
Rain forest
Two main types of biome in Nigeria are
Forest biome
Savannah biome
Savannah lies…….. Of the rain forest zone

Which biome consist mainly of short trees
Savannah biome
The three belt of savannah are
And they extend acrosss

Sahel desert
Example of trees found in sahel
Gum Arabic
Date palm
Acacias
How many biotic communities are there in the world and name them
Forest
