Feeding Relationships
Akopọ
Every organism depends on others for food, and those relationships link together into chains and webs that span entire ecosystems. Energy enters the living world through producers and flows upward through consumers, shrinking at every step.
In this lesson you will learn the names ecologists give to each trophic level, how to read and draw food chains, food webs, and pyramids, and the key reason why energy transfer between levels is so inefficient.
Awọn Afojusun
- Understand the names given to different trophic levels, including producers, primary, secondary and tertiary consumers, and decomposers
- Understand the concepts of food chains, food webs, pyramids of number, pyramids of biomass and pyramids of energy transfer
- Understand the transfer of substances and energy along a food chain
- Understand why only about 10% of energy is transferred from one trophic level to the next
