The Importance Of Organisms

Organisms require food resources to obtain energy for survival and reproduction. From the food that organisms consume they acquire energy needed for metabolic processes such as respiration, growth, and reproduction. Some organisms have the ability to get food resources better than others. The amount of food availability in a specific habitat is limited, therefore organisms that are not able to get the food resources most likely will go to a unfilled niche to get their food resources. Because there is no competition and there are a lot of unfilled niches, organisms that are not adapted to these niches can exploit them. Organisms that are able to adapt to these new niches, will eventually develop mutations that will help them exploit these niches and give them a big advantage over other organisms. Individual species that are able to adapt to a new environment have a higher chance of surviving because the competition is lower and more resource is available. So organism such as animals and plants rely on adaptive radiation mechanism to ensure they survive and pass on their genes to their offspring.

Adaptive radiation occurs when an organism evolves into a new form due to the change in their habitat or environment. Adaptive radiation also increases the diversity in each lineages. One example of adaptive radiation is the Darwin’s finches. In the 1830s Charles Darwin, a naturalist and geologist, set off on a voyage to the Galapagos Islands. He observed 13 species of finches on this island, each filling a different niche on different islands. After observing this he wanted to figure out why this happens. Charles Darwin observed and collected small birds that inhibited the islands and he also kept a record where he got the species from....

... and passing on their genes to their offspring.

Adaptive radiation is the processes where species evolve rapidly to exploit empty spaces. They form by many ways, one way is when there is an open niche an organism will move there and adapt to the environment. Another way is when an organism is living in a habitat where is being outcompeted by other organisms for food resource they are forced to move out and go to a different habitat. These organism will adapt to the new habitat and survive because there is less competition for food resource. Another way is by a storm, where a storm moves organisms out of their natural environment to a new environment and these organism adapt to survive in the new habitat. Organism’s main goal is to survive and pass on their genes to their offspring. Adaptive radiation is a key process which increases their reproductive successes.
