What is the absorption and distribution of materials within an organism?
Transport is the life process that includes the absorption and circulation of materials throughout an organism. Circulation involves the movement of materials to and from the cells, within cells, and/or throughout an organism.
What does distribution mean in biology?
1. The specific location or arrangement of continuing or successive objects or events in space or time. 2. The extent of a ramifying structure such as an artery or nerve and its branches.
What factors determine the distribution of organisms?
The biodiversity and distribution of organisms within an ecosystem is due to both abiotic (non-living) and biotic (living) factors….Abiotic factors
- light intensity.
- soil pH.
- soil moisture.
What affect the distribution of organisms in nature?
Biogeography is the study of the geographic distribution of living things and the abiotic (non-living) factors that affect their distribution. Abiotic factors can include temperature, moisture, nutrients, oxygen, and energy availability, as well as disturbances from events such as wind and fire.
What are the five levels of organization in order?
Summarizing: The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
What must be present for an organism to be considered living?
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
What are three types of population distribution?
- Uniform dispersion. In uniform dispersion, individuals of a population are spaced more or less evenly.
- Random dispersion. In random dispersion, individuals are distributed randomly, without a predictable pattern.
- Clumped dispersion. In a clumped dispersion, individuals are clustered in groups.
What are the two types of distribution?
As mentioned above, the two main types of distribution strategies are direct and indirect. There are also more nuanced types of distribution that fall into these categories — intensive, selective and exclusive distribution.
What 3 factors determine the distribution of a species?
Factors affecting species distribution
- climatic factors consist of sunlight, atmosphere, humidity, temperature, and salinity;
- edaphic factors are abiotic factors regarding soil, such as the coarseness of soil, local geology, soil pH, and aeration; and.
- social factors include land use and water availability.
How is species distribution determined?
The variance/mean ratio method focuses mainly on determining whether a species fits a randomly spaced distribution, but can also be used as evidence for either an even or clumped distribution. To utilize the Variance/Mean ratio method, data is collected from several random samples of a given population.
