Tropical and Temperate Savanna:

The location of savanna or grassland (on earth) is an important criteria in determining whether its tropical or temperate. To this end, the tropical savanna are found in the tropics while the temperate savanna are present in the temperate region

Note: The climate determines whether a region is tropical or temperate. This will be highlighted in the characteristics of both types of savanna.

Please read on the Introduction to Savanna here.

 

Tropical Savanna

The term tropics means "close to the equator". Tropical grasslands are located between 5o North and 20o South of the equator. This region lies between the Tropics of Cancer and the Tropics of Capricorn.

The tropical regions on earth where the grasslands are found include:

  • Central America
  • West Africa
  • Northern Australia
  • Some parts of East Africa
  • North West part of South America
  • South East Asia
  • Within Brazil

Please read on Ecology and Branches of Ecology here.


Characteristics of Tropical Savanna

  1. As the name suggests (grassland), it comprises of tall grasses.
    You can read on Swamp Forests and Types of Swamp Forest here.
  2. The annual temperature range is about 11oC.
    Please read on the Characteristics of Tropical Rainforests here.
  3. The extreme/high temperature ranges from 21oC – 30oC.
    Please read on Types of Desert and their Characteristics here.
  4. The annual rainfall is between 600 – 1500mm.
  5. Presence of few short and widely spaced trees here.
  6. In Africa and Australia, the grasses are called savanna. In Brazil, they are called campos while it's called ilanos in South America.
    Please read on the Concept of an Ecosystem here.
  7. The seasonal convectional rainfall has a single maximum. (Think of a single maximum as a 1 time period within a year where rainfall occurs at its peak).
  8. Examples of trees found in tropical savanna include acacia, baobab and shea-butter.

Please read on the Three main Types of Savanna here.

 

2. Temperate Grassland

A temperate (grassland) region lies between between the Tropic of Cancer and the Arctic Circle or between the Tropic of Capricorn and the Antarctic Circle. The temperatures here can be quite hot during the summer and extremely cold during winter.

Note: The growing seasons in a temperate grassland has a moderate temperature. They are found in the following areas:

  • North America
  • Argentina
  • Australia
  • South Africa
  • Asia

Please read on the Introduction to Biomes here.


Characteristics of Temperate Grassland

  1. It has a very hot summer (with temperatures above 25oC) and cold winter (with temperatures below 0oC).
  2. The vegetation (grasses) is dependent on the continental climate where the temperate grassland is present.
    You can read on the Components of an Ecosystem here.
  3. It has an average rainfall of 510mm.
  4. Heavy rainfall is not usually common here. Instead, the rainfall is light and convectional.
  5. The grasses have a uniform height and are shorter than those of the tropical grassland.
  6. The trees present here are few in numbers.
    You can read on the Differences between Plants and Crops here.
  7. The grasses are named differently within the various regions where they are found. The names are:

  • The Downs of Australia
  • The Steppe of Central Europe and Russia
  • The Veld of South Africa
  • The Pampas of Argentina
  • The Prairies of North America

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. Please read on sugars here


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

Please read the explanations on all the Basic Characteristics of Life here

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

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).

You can read on the introduction to Biology and the basic characteristics of life here

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
