6 Questions
Which process provides most of the energy for life processes in ecosystems?
Cellular respiration
What happens to the matter consumed at the lower level of a food web?
It is transferred up to higher levels
Why are there generally fewer organisms at higher levels of a food web?
There is less efficiency in transferring matter up the food web
Which process is responsible for providing most of the energy for life processes in ecosystems?
Combination of photosynthesis and cellular respiration

It is released as waste
Which organisms form the lowest level of the food web?
Plants
Study Notes
Energy and Food Webs
- Photosynthesis provides most of the energy for life processes in ecosystems.
- In a food web, matter consumed at the lower level is transferred to the next level, with some energy lost as heat.
Food Web Structure
- There are generally fewer organisms at higher levels of a food web due to energy loss at each trophic level.
- Producers, such as plants and algae, form the lowest level of the food web.
Test your knowledge on the cycles of matter and energy transfer in ecosystems, focusing on the importance of photosynthesis and cellular respiration. Explore how matter and energy are conserved and transferred through different levels of a food web. Gain a deeper understanding of how these processes impact the number of organisms at each level.
