Cycling materials and biodiversity GapFill

Plants are examples of  absorbersforestersproducersmanufacturers, meaning that they are responsible for making  chlorophylloxygenglucosenitrate. This contains energy which is passed through an ecosystem. The transfer of energy can be shown using a  flow chartfood chaingenetic fingerprintbiomass chain. Ecologists use several techniques to study ecosystems in order to work out how abundant or distributed species are. They use  compassestrichomesquadratsquadrangles or transects to perform these studies. In an ecosystem, the organisms that initially convert energy to food are eaten by primary, then secondary and tertiary  producersconsumersfeederspathogens. Organisms that eat others are called  predatorscatcherstrappershunters and these feed on  defendersvictimsherbivoresprey.

Materials in an ecosystem are limited and, in most cases, will be repeatedly recycled through the system; without recycling, resources such as carbon and water will not be available for other organisms. The carbon cycle removes  carbon dioxidestarchdustcarbohydrates from the atmosphere to be used by plants, whilst returning it to the environment in processes such as  respirationphotosynthesistranslationtranscription and decay.

Particular ways in which humans can affect the environment include waste management, such as causing pollution to land, air and  soilthe Sunwatergenes. Additionally, humans should reduce the excessive removal of trees from Earth - a process known as  unplantingdeforestationcullingdephotosynthesis. Failure to protect the environment, particularly by burning  solar powerfossil fuelsfusion reactorsbiomass, can cause global warming.
