What best describes diversity in terms of natural selection?
Diversity is the number of different role players (species) in an area. I like to think of diversity in the form of niches. The number of niches being filled in an ecosystem is directly related to the diversity.
Why are all organisms different?
Organisms differ because their DNA differs from one species to another, and from one member of each species to another. Organisms differ because according to 'Darwinian science' creatures evolve to fill niches of ecological web. In other words, when species evolve it is to become better adapted to their environment, have a greater aptitude at surviving and then feed on what used to be its predators- who in turn adapt to survive. As this system progresses entropy increases causing an ever increasing diversity of life-forms.
What are the main factors that contribute to the adaptive radiation of Darwin's finches?
Adaptive raidation is where you have lots of related species in a range of habitats. You often find adaptive raidation on islands or isolated places where you often have an odd mix of organisms eg there are many genera or families missing that you would normally expect....as a result there are often many niches in the environment that are not exploited by these so called "missing" species and so a genus may radiate to adapt and fill these niches.....the original species would have been very much like a finch you would expect on the mainland, but with varied niches and having different food sources available...oh the other major thing would have been compeition for food resources from other finches.....those that had the ability or traits to go for other ( untapped) food sources like harder/larger nuts etc would have survived better
Describe conditions that could make a new island a likely place for adaptive radiation?
Conditions that could make a new island a likely place for adaptive radiation would include being near a mainland so organisms can migrate as well as geographic isolation which prevents the splinter populations from breeding with the parent population on the mainland.
In what ways is food part of an organism's niche?
Food is part of an organism's niche because it is what is broken down to given an organism energy.
Is it possible for to organisms to live in the same habitat but have different niches?
yes it is possible
Can a habitat only have one niche?
No, a habitat can have multiple niches. Each niche represents a specific role or function that an organism plays within its environment. Different species within a habitat can occupy different niches, allowing for a variety of interactions and relationships to occur.
Can two species occupy different niches and the same habitat?
Yes, two species can occupy different niches within the same habitat as long as they have distinct roles and resources they utilize. This is known as niche differentiation, which allows species to minimize competition and coexist in the same environment.
How does an organism's niche differ from its habitat?
Niche: an organism's role in the environment. Habitat: specifically where it lives. For example, many organisms maybe have the same habitat (under a log, if we're considering insects), but as long as they occupy different niches, they will not be in competition.
What are the niches are?
An ecological niche is the role that an organism plays in its environment, included in that is it habitat and the interactions it has with other organisms in that environment.
Can a habitat only include one niche?
No, a habitat can contain multiple niches. A niche refers to the role or position that an organism has within its environment, including how it obtains resources and interacts with other species. In a diverse habitat, there can be many different niches occupied by different species, allowing for a variety of interactions and relationships within the ecosystem.
What is the place where groups of organisms live and grow called?
Niches within habitats are where organisms live. Organisms claim certain parts of their homelands in order to find their eating, exercising, mating, and resting needs met.
How can different niches several in the same habitat?
Different niches can exist in the same habitat through resource partitioning, where species evolve to use different resources or occupy different ecological niches within the same habitat. This can help reduce competition by allowing species to coexist by utilizing different food sources, habitats or behaviors. Additionally, species may adapt to different time periods for feeding or other activities, further reducing competition and enabling species to share the same habitat.
What are the key roles or niches that organism fill in their habitat?
The key roles or niches that organisms fill in their habitat are producers, primary and secondary consumers (herbivores, carnivores and omnivores), predators, prey, scavengers and decomposers.
What are the benefits of organisms occupying different niches?
Organisms occupying different niches reduce competition for resources, leading to more stable ecosystems. This also increases biodiversity and resilience to environmental changes. Additionally, it can promote coexistence and symbiotic relationships among species.
How does habitat and niches relate to eatch other?
There niche is how they survive and habitat is were it lives.
What are two different niches in a savanna habitat?
one niche is that lions eat zebras and zebras eat grass OR zebras drink water; a niche is like a role in a play; its the animals role in the eco system
