The longer the food chain, the: more energy reaches the top carnivores greater the production efficiency of birds fewer mutualistic interactions are possible greater potential for biological magnification
The longer the food chain, the:
- more energy reaches the top carnivores
- greater the production efficiency of birds
- fewer mutualistic interactions are possible
- greater potential for biological magnification
A food chain is the order of events within a ecosystem that describes how energy and nutrients are transferred between the living organisms in a systematic way. Food chain or food web is categorized based on the different trophic levels. In each trophic level 90% of the energy is lost while only 10% is transferred to the next level.
The order of a food is – sun (primary source of energy), primary producers (green plants), primary consumers, secondary consumers, and tertiary consumers.
So, 1st option is incorrect because the longer the food chain, less energy reaches the top carnivores because in each trophic level about 90% of the energy is being consumed while only 10% is transferred to the next level.
