The answer is; B
When autotrophs and chemotrophs (primary producers) covert abiotic factors to biotic elements, this energy are passed up the food chain and food web through interaction with other organisms. These interactions include predation and parasitism. Â Since matter and energy cannot be destroyed or created, it is only cycled through the trophic levels. In the transfer of this matter/energy from one trophic level to another, most of the energy is lost in the environment through inefficiencies. Â
Answer: Option D
Explanation:
The matter is recycled through biogeochemical cycle and food web. The producers make food by the help of the process photosynthesis.
The food is eaten by animals. Then after completing their life cycle plants and animal die.
The died plants and animal eat up the decomposer which is present at every level of food web.They recycle the matter back into the soil.
The biogeochemical cycle helps in recycling the carbon, nitrogen phosphorous on earth. There is a continuous movement of matter on earth.
hence, the matter is recycled through the food web and biogeochemical cycle.
