What is Ecology?

Ecology is considered as one of the major branches of biology. The word ecology is derived from the Greek word oikos (οแผถκος) which means house or home or dwelling place or environment. Based on this knowledge, the term ecology can be defined thus:

Ecology is a field of study in biology that deals with the relationships and interactions between living organisms and their environment.

Note: Some biologist will refer to ecology as an environmental biology.

Please read on Important Ecological Concepts here.

We see ecology around us on a daily basis. For instance, if you had taken some time to observe how fowls, goats, sheep and other domestic animals around you interact with their environment, then that's a feel of ecology.

Please read on the Concept of an Ecosystem here.

Ecology is an entirely field in biology and can thus be a very broad subject of discussion. For instance, the organisms found in the desert biome will have to interact with their desert environment; and this will be quite different in the manner at which aquatic organisms, swamp and forest organisms interact with their respective biome. You probably may have seen some of these interactions on televison through the animal documentary channels.

Please read on the Swamp Forest Biome here.

You can read on the Desert Biome here.

 

Branches of Ecology

Ecology can be put into two main branches or divisions. These are:

1. Autecology

Autecology is a branch of ecology that deals with the study of a single organism and the interaction with its environment.

An instance of autecology is when one studies a single hen and it's environment.

You can read on some Amazing Facts in Biology here.

The above instance can be quite practicable, especially by students living in rural areas.

 

2. Synecology

This branch of ecology is concerned with the study of inter-relationships between two or more species of organisms living together in an environment.

An instance of synecology is the study of organisms living in the savanna.

Please read more on Savanna (Grassland) here.

Note: The savanna organisms will include the grasses, zebras, buffaloes, lions and so on.

Amazing facts in Biology

Women have more pain receptors than men

It's crucial you finish your antibiotics.

If you stop taking your antibiotics before you're supposed to, any bacteria that didn't get killed can develop an immunity to that antibiotic and become a super-strain, making it much difficult to kill in the future. So keep taking your antibiotics pill, even if you feel better.

Although rare, women can still give birth when they die. This is known as coffin birth

Men can actually get aroused post moterm. This is called priapism

There are more bacteria on your body that the entire human beings on earth

๐ŸฆŸ Mosquitoes ๐ŸฆŸ have killed more people than all the wars in history put together

The human ๐Ÿง  brain ๐Ÿง  does not feel pain. For this reason, neurosurgeons can perform brain surgery while the patient is awake

๐Ÿฆ˜ Kangaroos ๐Ÿฆ˜ can't walk backwards

There is an unusual plant found only in Australia's Daintree Rainforest. It's called the idiot fruit

Although the hippopotamus has a large head with a bulky body on stumpy legs, it still runs faster than a man


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 ๐Ÿƒ 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 (๐ŸŒฒ 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) ๐ŸŒฑ๐Ÿ๐Ÿ“. 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
