Explanation:

In a food web, producers (like the low grass here) capture energy from the sun via photosynthesis. A wildfire burning 80% of low grass reduces the producer biomass. Primary consumers (herbivores that eat grass) will have less food, so their population may decline. This affects secondary consumers (carnivores/omnivores that eat primary consumers) as their prey becomes scarce, potentially reducing their populations too. The energy flow is disrupted as less energy is available at the producer level to pass up the trophic levels.

Answer:

A wildfire burning 80% of low grass (a producer) reduces the energy - capturing base of the food web. Producers convert solar energy to chemical energy in organic matter. With less grass, herbivores (primary consumers) that rely on grass for food face a food shortage. Their population may decrease, which then impacts secondary consumers (organisms that eat primary consumers) as their prey becomes less abundant. Overall, the amount of energy available to flow through the trophic levels (from producers up to higher - level consumers) is reduced, disrupting the normal energy flow in the food web.
