Explanation:

1. Producers convert sunlight to organic matter via photosynthesis.
2. Lions and wolves are predators that hunt other animals.
3. Fungi, bacteria, and some insects are decomposers breaking down dead matter.
4. The producer level consists of organisms making energy - rich compounds from sunlight.
5. Predatory fish at the top of a marine food web are crucial and over - fishing can disrupt the ecosystem.
6. Sea otters control sea urchin populations to prevent overgrazing of kelp.
7. In Yellowstone, the absence of wolves led to an increase in elk population as wolves prey on elk.
