Name the difference between a food chain and a food web. Also state a few animals role in the food chain and food web.
Brums [2.3K]
The food chain in a visual representation of how energy is flowed through out a specific environment. While it is very similar to the food web, the main difference is that the web gives a more broad wide range of organisms and it is more specific with what eats what. The second part of your question about a few animals roles umm... Grass is a producer which has the role of feeding primary consumers, it is the base of the chain or web without it the whole thing would collapse. Tertiary consumers such as owls have the role of eating secondary consumers. I always thought of it like the tertiary consumers are population control since nothing eats them they have no responsibility to feed other organisms just make sure that secondary consumers don't overpopulate.

Read the section “Gaining Biodiversity.” Describe geographical isolation and competition. (Site 2)
velikii [3]
<span>Globally, diversity naturally has increased over time, though the great mass extinctions have decreased it for a while. The most famous of the mass extinctions is the one that claimed the dinosaurs, but we are currently in the midst of a human-created mass extinction. Local diversity, on the other hand, is constantly increasing and decreasing at very short time scales. There are many factors that affect diversity, and the major natural circumstances are given here. Human-generated impacts on diversity have almost always been negative, and are covered in the Conservation Issues section.</span>
