Ecology

Ecology (Life Sciences) 5. Organisms in ecosystems exchange energy and nutrients among themselves and with the environment. As a basis for understanding this concept: a. Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs. b. Students know matter is transferred over time from one organism to others in the food web and between organisms and the physical environment. c. Students know populations of organisms can be categorized by the functions they serve in an ecosystem. d. Students know different kinds of organisms may play similar ecological roles in similar biomes. e. Students know the number and types of organisms an ecosystem can support depends on the resources available and on abiotic factors, such as quantities of light and water, a range of temperatures, and soil composition. =introduction= today im going to be telling you about cycles in the biosphere and the prosses of photosyntesis and the food web and how the food web works. For example food energy is pased around from human beings to animals and the prosses of photosynthesis is also works with the producers,primary sources, and secondary sources,and the amount of energy that is passed down by the consumers so keep reading to find out the awesome facts of ecology.

=cycles in the biosphre= the cycles in the biosphre are produced by photosynthesis for example photosintesis is started by respiration of any human being and produced into carbon dioxide and then eventually producred in to oxygen.

photosyntesis

 * carbom dioxide
 * water
 * energy
 * glocuse
 * oxygen

respiration
=food energy= food for animals is a sourece of energy and they are cycles and they are by order from primary sources to get food from one animal from another and theirone example is that any tipe of rodent eats up some tipe of seed that have fallen from a tree its eaten and then the rodent is hunted by some tipe of scavenger and eventually eaten and digested and then the the the digestetd item is used as fertiliser and then helps trees and plants grow thats how the food energy works. = =
 * glocuse
 * oxygen
 * carbon dioxide
 * water
 * energy

 * decomposer /live by breaking apart once living matter
 * energy pyramid /shows the energy of the availability of enenrgy in the ecosystem
 * food web / are about wet land or dry land and the bodies of of fresh water
 * producer / the producers include plants,algae,and some bacteria
 * scavenger / is animal that eats the meat of dead animals some examples are voultures,hyenas and ravens
 * trophic level /producers make up the lowest thropic level
 * consumer
