HELP ASAP A food web is more realistic than a food chain for showing the feeding relationships in ecosystems because:

It compares the number of consumers to the number of microorganisms in an ecosystem

Food chains use only small animals.

Producers are usually eaten by many different consumers and consumers are eaten by more than one predator

a food web explains why there are more producers than consumers.

Food chains show just a single feeding pattern. Each organism has a single role in the ecosystem. Food chains make it easier to visualize trophic levels, or how energy moves through the ecosystem. ... This is why webs are considered to be more realistic than simple food chains.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
