The present-day distribution of organisms is shaped by a combination of historical factors, such as continental drift and glaciation, as well as contemporary influences like climate, habitat availability, and human activities. Biogeographical patterns reveal distinct ecosystems and biodiversity hotspots around the world, with species often limited to specific regions due to ecological niches and evolutionary adaptations. Additionally, human-induced changes, including urbanization and climate change, are altering the natural distribution of many organisms, leading to shifts in habitats and species interactions. Overall, the distribution is dynamic and continues to evolve in response to both natural and anthropogenic factors.

What is the science that studies living organisms in space?
Ecology, or ecological science, is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment.
How do vestigial structures indicate that present day organisms are different from their ancient ancestors?
Vestigial structures are remnants of organs or features that were functional in an organism's ancestors but have reduced or lost their original function over time. The presence of these structures suggests that present-day organisms have undergone evolutionary changes from their ancient ancestors. These structures provide evidence for common ancestry and support the theory of evolution.
Where is gastrovascular cavity found?
The gastrovascular cavity is found in certain simple organisms, primarily in the phylum Cnidaria, which includes jellyfish, corals, and sea anemones. It serves as both a digestive and circulatory system, allowing for the distribution of nutrients and the removal of waste. Additionally, it is present in some flatworms, providing a similar function in these organisms.
Where is cell present?
Cells are present in all living organisms, from the simplest single-celled microorganisms to complex multicellular organisms like plants and animals. Cells make up the basic units of structure and function in living organisms.
Are all naturally-occurring elements are essential to living organisms?
No , only 2 dozen are present in organisms .
What evidence do you not use to construct a cladogram?
Ecological roles of present-day organisms.
Present- day taxonomists attempt to group organisms according to what?
Present-day taxonomists attempt to group organisms according to their evolutionary relationships, genetic similarities, and shared characteristics. This helps to organize and classify living organisms into hierarchical categories based on their shared ancestry and unique characteristics.
What is the science that studies living organisms in space?
Ecology, or ecological science, is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment.
What is a reason of cluster distribution in organisms?
One reason for cluster distribution in organisms is the need for resources. Cluster distribution allows organisms to maximize their access to resources such as food, water, or nesting sites. By living in close proximity to one another, organisms can benefit from shared resources and protection from predators. In addition, cluster distribution can facilitate social interactions and cooperative behaviors, enhancing the survival and reproductive success of individuals within the cluster.
How do scientists determine the distribution of organisms in an environment?
they test
What is Paleobiogeography?
Study of the geographical distribution of ancient organisms.
What is a spatial distribution in organisms?
Spatial distribution in organisms refers to how individuals are arranged in a given area. This can be random, uniform, or clumped. Factors influencing spatial distribution include resources availability, environmental conditions, and social interactions.
Why can ecology be described as a holistic science?
Ecology, or ecological science, is the scientific study of the distribution and abundance of living organisms and how the distribution and abundance are affected by interactions between the organisms and their environment.
Is ribose present in the DNA or RNA of living organisms?
Yes, ribose is present in the RNA of living organisms, but not in the DNA.
How water affects the distribution of organisms?
Water availability is a critical factor in determining the distribution of organisms. Some organisms require specific water conditions and will only be found in areas with the right level of moisture. Changes in water availability due to factors like precipitation patterns or human activities can lead to shifts in the distribution of organisms, impacting ecosystem health and biodiversity.
What is the distribution of water in the hydrosphere?
The distribution of water in the hydrosphere is primarily in the form of oceans and seas (97.5%). The remaining water is found in glaciers and ice caps (1.7%), groundwater (1.7%), and freshwater lakes, rivers, and streams (0.02%). Water is also present in the atmosphere and living organisms.
