What moves through the community from one trophic level to another as organisms feed on one another?
TEA [102]

Energy moves from one trophic level to another as organisms feed on one another.

Explanation:

Energy flows from one trophic level to another in a food chain. according to the ten percent law, only ten percent of the total energy passes onto the next trophic level. While studying the energy flow model two aspects should be taken under consideration. Firstly, the flow of energy is unidirectional and passes on from autotrophs to primary consumer and then secontary, tertiary so on. Secondly the amount of energy decreases at succesive trophic level.

Biocentrism is not considered when looking at life-centered environmental ethics
Murljashka [212]

The given statement is not true.  

Biocentrism in an ecological and political sense, as well as, in an ethical perspective encompasses intrinsic value to all the living creatures. It is an understanding of how the earth functions, mainly as it associates with biodiversity.  

The term biocentrism covers all the environmental ethics, which outspread the status of the moral object from human beings to all the living creatures in nature. Biocentrism witnesses each species as a component of the living biosphere.  

It witnesses the outcomes of minimizing biodiversity on both the large and small scales and emphasis towards the innate values all the species exhibits towards the environment.
