True
Why is a food web more realistic than a food chain?
Because animals often eat more than one kind of food,like Omnivores.And food webs show all the possible feeding relationships in an ecosystem
In a food chain, fish eat algae, big fish eat small fish. If the number of small fish decrease dramatically,what will happen to the big fish and algae?
Big fish will decrease,because they have less food.
Algae will increase,because fewer fish eat them.
What might happen in a food web if one species increase vastly?
If one species increases too much, it may overuse its food source, causing that species to decrease.
This can also affect predators and other organisms in the food web, possibly throwing the ecosystem out of balance.
