- Hello, citizens of Red Oak, TX. Today, I will explain to you the questions i have been asked to answer. Question #1, Why is competition for biotic resources a key factor in the success of an organism or a population in an ecosystem?
- Well, here's the thing about competition for biotic factors: biotic factors are LIMITED. Competition is important towards biotic factors, because they are limited, so more competition means less eating of the biotic factors, which means more of them, which means they can supplement the amount of organisms eating them, which is the results of competition.
- But you have to remember that those were biotic factors. So question #2, Why is competition for abiotic resources a key factor in the success of an organism or a population in an ecosystem?
- well, these kinds or resources aren't limited. so when organisms compete for it, it doesn't go away, and the dominant organism can pass on its good genes to its offspring, so it can be more successful in growing up and living. This is a part of competition being a limiting factor.
- The 3rd and last question, how can the concept of organisms or populations filling a specific niche in an ecosystem help explain how competition between organisms can develop?
- When a niche forms, another organism or species could already have that niche, so they will start competing over food. Here's an example of this: let's say a cardinal has a small beak, but slowly over time, the beak gets bigger. as the beak gets bigger, the cardinal can use it to break and eat bigger nuts. But now that the cardinal changed it's beak, its competing for a new food source.
