Question

1. write a paragraph explaining how energy flows through an ecosystem using the following terms: energy pyramid, trophic level, producer, consumer, decomposer

Explanation:

Energy flow in an ecosystem starts with producers (like plants) at the first trophic level. They convert sunlight into energy via photosynthesis. Consumers (herbivores, carnivores, omnivores) at higher trophic levels eat producers or other consumers. Energy transfer is inefficient, shown in an energy pyramid where each level has less energy. Decomposers (fungi, bacteria) break down dead organisms, recycling nutrients and energy back to the ecosystem.

Answer:

Energy flows through an ecosystem beginning with producers (e.g., plants) at the first trophic level. They capture solar energy through photosynthesis. Consumers (herbivores, carnivores, omnivores) occupy higher trophic levels, feeding on producers or other consumers. Energy transfer between trophic levels is inefficient, as depicted in an energy pyramid (with less energy at each successive level). Decomposers (such as fungi and bacteria) break down dead organisms, recycling nutrients and energy back into the ecosystem, thus completing the energy - flow cycle.
