Ecosystem Pictures (not done)
By; Joey Patterson
The purpose of this project is to teach about the parts of ecology and describe the function of each part. In this presentation you will find many pictures that represent each part followed by a short description that explains that part and its purpose.
Where two different species of organism work together and both benefit.
Where two different species of organisms work together and one benefits and one gains nor loses anything.
A predator-prey relationship is when one species is hunted and killed for food by another so it can fill its needs of energy so it cn survive.
An autotroph is an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
A heterotroph is an organism deriving its nutritional requirements from complex organic substance.
Uniform dispersion is an organism in a population that is equal to its peers.
Random Dispersion is the tendency for populations to be found randomly about their habitat. In immobile species, this is usually caused by their ability to live anywhere in a given habitat, except, they are limited to growing wherever they are first set root (which is usually caused randomly, from spores drifting in the wind to seeds falling and tumbling on the ground). In motile populations, individuals are able to move about their habitat, so that at any given instance, they can be found anywhere about their environment.
Clumped distribution is the most common type of dispersion found in nature. In clumped distribution, the distance between neighboring individuals is minimized. This type of distribution is found in environments that are characterized by patchy resources.
Density Dependent Factor
Any factor limiting the size of a population whose effect is dependent on the number of individuals in the population. For example, disease will have a greater effect in limiting the growth of a large population, since overcrowding facilitates its spread.
Density Independent Factor
Both living and non-living things can influence the size of a population of organisms. Some things that happen to populations, such as disease and parasites, depend on the size of the population to be successful at causing destruction. Things and events that limit the size of a population regardless of the density of the population are called density-independent factors.
Competition is an interaction between organisms or species in which the fitness of one is lowered by the presence of another.
The cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
The series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
The series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
The phosphorus cycle is the bio-geochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
A species not native to habitat its in.
An energy source that can always be used.
