Tropical Rainforest:

The tropical rainforest (also spelt as tropical rain forest) is considered as one of the major biomes of the world. Other biomes include savanna or grassland, desert, swamp forests, afro-alphines and montane forests.

Recall that a biome, also called a biotic community refers to the largest natural community of different organisms interacting and living in the same environment.

Please read more on the Concept of a Biome here.

Interestingly, the tropical rainforest ranks among the biome with the largest biotic community. Their biotic (living) community ranges from the colorful species of birds, the tall and gigantic trees, millions of insects, numerous species of reptiles and so on.

Although the tropical rainforest accounts for only 6% of the solid solid part of earth (lithosphere), it serves as a home to about 80% of the world's recognized specie of animals.

Please read on the Ecosystem here.

The tropical rainforest which is popularly known for its characteristics heavy downpour (rainfall), tall canopy trees and variety of animal species is located in the tropical regions (tropics) around 28o North and South of the Equator between the Tropic of Cancer and Tropic of Capricorn. These regions of the equator include:

  • Amazon Basin of South America
  • Coasts of West Africa
  • Zaire Basin of Central Africa
  • Central America and Mexico
  • Australia
  • Pacific Islands
  • Within Malaysia

You can read on the Swamp Forest Biome here.

Please read on the Characteristics of Tropical Rainforests here.

The temperatures of the tropical rainforest can be very wet and hot at different times. It is believed to habour the oldest types of vegetation (to this day) on terrestrial ecosystem. Regardless, the rainforest still continues to evolve and change, such that the present tropical rainforests may be slightly different from its past composition (in terms of vegetation and organisms dwelling in them).

Please read on Tropical Savanna and Temperate Savanna with their Characteristics here.

Note: The tropical rainforest is crucial to man's survival. This is summarized in their importance below:


Importance of Tropical Rainforest

The importance of tropical rainforest is the same thing as its functions or benefits. They are highlighted below:

  1. They serve as a natural reservoir for important medicinal plants.
    Please read on the Differences between Plants and Crops here.
  2. They generate a significant amount of earth's oxygen through the photosynthetic activities of its numerous plants.
    Please read more on the Functions of the Atmosphere here.
  3. They provide valuable forest resources like timber (which can be used for construction, building and furniture making).
    Please read on Hardwood and Softwood with their Characteristics here.
  4. They remove a significant amount of carbon(IV)oxide from the atmosphere. This function acts as a check to earth's global warming.
  5. The act as buffer against flood, droughts and water erosion.
    Please read on Erosion here.
  6. Its trees acts as agents of wind break. This function prevents wind erosion in nearby farmlands.
  7. Its dense vegetation acts as buffer against flood and water erosion by holding back the flow of water.

Amazing facts in Biology

Male Seahorses actually give birth to their young ones, NOT the female

All babies are born with blue eyes

Research made at the University of Vienna suggested that yawning may play an essential role in cooling the brains

All voluntary and concious activity of right handed people are controlled from the left part or hemisphere of the brain

A snail can actually sleep for 3 years 😁

An adult human being is composed of about 60% water. In fact, a newly born baby is composed of about 80% of water. This will drop to 65% after a year and finally to about 60% as the child ages

Without saliva, food can never be enjoyed. Food becomes tasteless since saliva is needed to dissolve the chemicals present in food onto the tongue’s taste buds.

Saliva also contains an enzyme called salivary amylase or ptyalin which helps to digest cooked starch to maltose.

Maltose is a double sugar or disaccharide.

NOTABLE POINTS IN Biology

For a thing to be considered Living, it must possess all the Basic Characteristics of Life. These include:

  1. Movement

  2. Respiration

  3. Nutrition

  4. Irritability or Sensitivity

  5. Growth

  6. Excretion

  7. Reproduction

  8. Death

  9. Adaptation

  10. Competition

During strenuous exercises like sprinting or 🏃 running, your body may actually work in the shortage of oxygen. During this time, your body owes oxygen (called oxygen debt) and it must be replenished or repayed after the exercise is stopped. This is why you breathe excess of oxygen after you stopped the exercise.

This is the concept of anaerobic respiration

Food Chain - Len Academy

A food Chain is a diagram that shows the relationship between plants and animals within a habitat on the basis of how they rely on each other for food.

Note: Habitat is a place where an organism live. It is of three types:

  • Terrestrial (Land)
  • Aquatic (Water)
  • Arboreal (🌲 Treetops)

You can read on Food Chain here

The term Biology originated from two Greek words. They are:

  • Bios: means life.
  • Logos: means knowledge or to study.

Biology can therefore be defined is the study of life

Anything that has life is generally considered as a living organism (or organism) 🌱🐐🐓. All living organisms must be able to carry the following activities:

  1. Movement
  2. Respiration
  3. Nutrition
  4. Irritability or Sensitivity
  5. Growth
  6. Excretion
  7. Reproduction
  8. Death
  9. Adaptation
  10. Competition

The above listed points are often regarded as the basic characteristics of life. You can memorize them using the acronym (MR. NIGER DAC).

The gas used in the manufacture of food by plants is Carbon dioxide or Carbon(IV)oxide or CO2

Plants manufacture food through a process called photosynthesis.

Please read on photosynthesis here

Note: Plants are the only orgnisms that take away CO2 from the atmosphere
