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 or 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 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

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 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 savanna and its characteristics here.

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. They act as buffer against flood, droughts and water erosion.
    Please read on erosion here.
  6. Tropical rainforest trees act as agents of wind break. This function prevents wind erosion in nearby farmlands.
  7. The dense vegetation present in the tropical rainforest acts as buffer against flood and water erosion by holding back the flow of water.

Amazing facts in Biology

Panda eating bamboo - Len Academy

99% of a panda's diet is bamboo. They may eat fish or other small animals occasionally

When attacked by insects, lima beans plant will often command parasitic wasps to their defence.

When the leaves of the lima bean's leaves are eaten by insects, the plant gives off a substance that signals parasitic wasps to swam in, destroying its enemies (the leaf-eating insects) in the process

Frogs drink water through their skin

Armadillos - Len Academy

Armadillos are western mammals known for their unique armor-like shell which are bulletproof

Polka-dotted zebra - Len Academy

Although zebras are known for their characteristics black and white stripes, we still have some polka-dotted zebras

Charles Darwin is a British naturalist and biologist who contributed greatly into the study of evolution. According to research, he frequently ate the animals he studied

Lungs are the only human organ that can float on water

Unlike most snakes that lay eggs, anacondas give birth to live babies

Shrimp - Len Academy

A shrimp's heart is in its head

Women have more pain receptors than men


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 as 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

It is noteworthy to state that plants are the only orgnisms that take away CO2 from the atmosphere
