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.

Description
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.
