Energy flows through different steps in a food chain, and it usually gets less at each step.

1. Trophic Levels:

   • Producers: These are plants that take in energy from the sun through a process called photosynthesis.
   • Primary Consumers: These are herbivores, like rabbits, that eat plants. They get about 10% of the energy from the producers.
   • Secondary Consumers: These are carnivores, like foxes that eat rabbits. They only receive about 1% of the energy from the plants.

2. Energy Loss:

   • At each level, some energy is lost because of how living things use energy. This includes energy used for movement, heat, and waste.

So, as energy moves up the food chain, only about 10% goes to the next level!
