Biotic Vs. Abiotic

Biotic Component

Biotic Components are the living things that shape an ecosystem.


Biotic Components are contrasted to Abiotic Components which are non-living components of an organism's environment, such as temperature, light, moisture, air currents, etc.

Biotic Components usually include:

Producers, i.e :autotrophs e.g. plants, they convert they convert the energy from photosynthesis, or other sources such as hydrothermal vents into food.

Consumers, i.e : heterotrophs e.g. animals, they depend upon producers (occasionally other consumers) for food.

Decomposers, i.e :detritivores e.g. fungi and bacteria they break down chemicals from producers and consumers (usually dead) into simpler form which can be reused.


Biotic factors are any living component that affects another , including animals . For example:

1.Plant grows

2.Plant is eaten by a rabbit

3.Rabbit is eaten by a cat

4.Cat is eaten by a Jaguar

Abiotic components

Abiotic components are non-living things that living organisms need to survive such as:

1.Water

2.Air

3.Temperature

What does being alive means?

The characteristics of life-living beings

• Every Living being in earth is made by cells:

  Unicelular 

 Pluricelular

• Living Beings can Organize

• They Grow And Develop

• They respond to stimulation 

• Living beings reproduct. Every living being and life form has one type of reproduction and those are:

 Asexual: The living form reproduces without the need of a female or male specie, they are independent.

 Sexual: The living Form needs another specie of the same to reproduce such as male or female humans

• Living Beings Require energy in order to live this energy can be obtained by two forms:

     Digestion: The living being process the food for living

     Photosynthesis: The living being can obtain energy by the power of the sun extracting:

• Homeostasis: is the abiliti to mantain a stable body according to the living thing needs

Theories of Creation

From the beginng of time men had always wondered where do they come from. This has caused many theories trying to explain it. However non of this had been proved to be real.
The most renowned ones are the following.

Creationist theory:

“Creation of the earth by god”, it is a group of beliefs inspired by religious doctrines. The term "creationist" is to describe a proponent of creationist. There are many types of creationism. The term became particularly associated with Christian fundamentalist movements that insisted on a literal interpretation of the Genesis creation narrative and likewise opposed the idea of human evolution. Discoveries of new lands brought knowledge of a huge diversity of life. Natural theology developed the study of nature with the expectation of finding evidence supporting Christianity

Panspermia theory

It proposes that the life could have its origin in any part of the universe (Life originated elsewhere and was "seeded" onto Earth by way of comets or meteorites)
Panspermia is the proposal that microscopic life forms could survive the effects of space.They became trapped in debris that was ejected into space after collisions between planets and small celestial bodies that harbored life.

The Big Bang theory 

Proposes that the universe was created by a huge explosion. Also suggests that at some moment all matter in the universe was contained in a single point, which is considered the beginning of the universe. After the initial expansion, the universe cooled sufficiently to allow the formation of subatomic particles, including protons, neutrons, and electrons. Though simple atomic nuclei formed within the first three minutes after the Big Bang it was necessary thousands of years before the first electrically neutral atoms formed. The majority of atoms that were produced by the Big Bang were hydrogen, along with helium and traces of lithium. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies, and the heavier elements were synthesized either within stars or during a supernovae.

Physical-Chemical Theory

This theory tells us that during the origin of life in earth, the atmosphere contained He & H2, tis gases were dispesed beacuse by those times earth lacked of gravity. After years passed, volcanoes erupt and other new gasses were liberated: NH3, CO2, CH4. This gases combined with each other and with the help of electrical shocks, aminoacids where created. With aminoacids simple organisms were created. this first organisms are called primitive cells.

 

 

Abiogenesis

According to some scientists, b efore life was created there was only geology and chemestry. This two were affected by water wich came through meteorites that chrashed the earth long time ago. After water and other chemicals and gases mixed toghether aminoacids, proteins, sugars and finally DNA. After millions of years of evolution this aminoacids, protein and DNA became bacterias and cells, and after more millions of years those bacterias and cells became animals, plants and humans.
