Relationships within an ecosystem.
Energy and Matter Flow in Ecosystems
What is the relationship between photosynthesis and respiration? Students will compare the process of cell energy as they pretend they have traveled to a distant planet and discovered an alien life form. What gases are found on this planet and what do these aliens inhale and exhale? Students will learn about the relationship between photosynthesis and respiration in this guided notes sheet and lab activity or demonstration.

In topic , an was defined as a dynamic entity composed of a biological and its associated environment. Often the dynamic interactions that occur within an ecosystem are numerous and complex. Ecosystems are also always undergoing alterations to their biotic and abiotic components. Some of these alterations begin first with a change in the of one component of the ecosystem which then cascades and sometimes amplifies into other components because of relationships.
In recent years, the impact of humans has caused a number of dramatic changes to a variety of ecosystems found on the Earth. Humans use and modify natural ecosystems through agriculture, forestry, recreation, urbanization, and industry. The most obvious impact of humans on ecosystems is the loss of . The number of caused by human domination of ecosystems has been steadily increasing since the start of the . The frequency of species extinctions is correlated to the size of human population on the Earth which is directly related to resource consumption, land-use change, and environmental degradation. Other human impacts to ecosystems include species invasions to new habitats, changes to the abundance and dominance of species in communities, modification of , modification of hydrologic cycling, pollution, and climatic change.

are much more complex than simple sediments. They contain a mixture of weathered rock fragments, highly altered soil mineral particles, , and living organisms. Soils provide , water, a home, and a structural growing medium for organisms. The vegetation found growing on top of a soil is closely linked to this component of an ecosystem through nutrient cycling.
The atmosphere provides organisms found within ecosystems with carbon dioxide for and oxygen for . The processes of , , and cycle water between the atmosphere and the Earth's surface.

Once fixed by plants, organic energy can move within the ecosystem through the consumption of living or dead organic matter. Upon decomposition the chemicals that were once organized into organic compounds are returned to their inorganic form and can be taken up by plants once again. Organic energy can also move from one ecosystem to another by a variety of processes. These processes include: , animal harvesting, plant harvesting, plant of , , and . The following diagram models the various inputs and outputs of energy and matter in a typical ecosystem (Figure 9j-2).

c) What are the applications (industrial, academic, intellectual or otherwise) of the research?
d) How are humans creating their own version of the trait/skill/adaptation or incorporating it into their own research?
Creating a Climate Change Model by Biology with Brynn and Jack
Organisms that require fixed energy found in organic molecules for their survival are called . Heterotrophs who obtain their energy from living organisms are called . Consumers can be of two basic types: Consumer and decomposers. Consumers that consume plants are know as . are consumers who eat herbivores or other carnivores. or are heterotrophs that obtain their energy either from dead organisms or from organic compounds dispersed in the environment.

Living organisms can use energy in basically two forms: or . Radiant energy exists in the form of , such as light. Fixed energy is the found in organic substances. This energy can be released through . Organisms that can take energy from inorganic sources and fix it into energy rich organic molecules are called . If this energy comes from light then these organisms are called . In most ecosystems plants are the dominant photosynthetic autotroph.

Only a very small proportion of the sunlight received at the Earth's surface is transformed into biochemical form. Several studies have been carried out to determine this amount. A study of an Illinois cornfield reported that 1.6% of the available solar radiation was photosythetically utilized by the corn. Other data suggests that even the most efficient ecosystems seldom incorporate more than 3% of the available solar insolation. Most ecosystems less than 1% of the sunlight available for .
