Biotic vs Abiotic


As defined biotic organisms are related or resulted from living thing as in they move, reproduce, grow, respire, they excrete, they take in nutrients and have sensitivity. All characteristics of which this plant below contains allowing us to consider it to be a biotic organism.

Abiotic organism are the opposite of biotic organisms as in their non living. They do not consists of anything biotic organisms have, most of these examples are man made. An example would be the desk below, which we use for sitting.

Autotrophs vs Heterotrophs


Autotrophs are organisms that produce their own food. They do not necessarily depend on anyone or anything for the creation of their food other than the Sun. the primary source of what all living things depend on. The plant below is a primate example because it not only creates food for itself but also creates food for humans and other animals.

Heterotrophs are organisms that do not create their own food as in they depend on other living things or resources for their food. A good example would be the fish below, it does not create its own food but sometimes depend on humans to feed it like the pet fishes or it depends on eating plankton like the ocean fishes. Our example below is a pet fish which we humans feed.

Predator and Prey

A predator is an organism that preys on others they tend to destroy, devour or decimate the other organism. While the prey is the organism that is hunted and killed by the predator mostly for food. This is most common in living things relationships. But unlike our example below that isn't a living the do have the same relationship. The trash can is the Predator seeking out the paper trash who is the prey. Once the paper is thrown into the trash can it has been devoured. Thus completing their predator prey relationship

Mutualism as said in its root word "mutual" by definition is something done by two partners that benefits them equally. Mutualism benefits both organisms. The example below is Mooyah it is a good example because it benefits both the customers and the owners. The customers are served food to satisfy their hungers and drinks to quench their thirsts while the owners are benefited because they are given money from the customers to help pay their bills and live their lives

Commensalism is when one organism is benefited while the other organism is neither benefited or affected. The MacBook is a good example because as we humans use it we are benefitting information and knowledge from it. While the MacBook is unaffected by what we are doing.

A non symbiotic relationship is when one specie (the parasite) benefits from the other, while the other is negatively affected (the host). The parasite benefits for it self while it causes harm to the host. Our example below is the weed surrounding the tree they take the nutrients the tree is supposed to have and use it all for themselves. Thus weakening the tree and depleting it of its nutrients.

Food Chain

A food chain is a continuous series of organisms that depend on the other for food they need. As the environment expands so does the food chain. The example below consists of the common one , our producer is a plant which also happens to be an Autotrophs creates the food that feeds the caterpillar. The caterpillar is the primary consumer because it eats directly from the producer while the secondary consumer is the bird which eats the caterpillar and last but not least is the Tertiary consumer is the cat. It eats the bird, this is a continuous chain that goes on and on providing food for each organism.

Carbon cycle

Carbon a chemical molecule that is not necessarily bad for humans make up the carbon cycle where is the process by which the carbon compounds are infused into the environment in many ways below are our examples. The banana is rotting, as the banana is decomposing carbon is released into the atmosphere another example would be the thermostat we use it to change the conditions of the air when it is hot or cold this way carbon goes into the air. Burning is another example because the cooker is turned on and as the fire starts to burn the carbon gets released. And finally the nose as we commonly know we breathe in oxygen and breathe out carbon dioxide this is another way it is released into the atmosphere.

One main way Carbon dioxide is taken out of the atmosphere is by plants they create the oxygen we breathe in by expelling it and taking in the carbon dioxide we take out.
