Which ecosystem, a park or a forest, has a more complex food chain?

The forest has a more complex food chain, since there are many different species of animals and plants in forest communities and the relationship of relationships between participants. Branched food chains, the presence of a different food base, many species and the nature of education – all this makes the ecosystem sustainable. A park is a man-made system in which one or more species predominate, the number of animals and plants is less, the food chains are shorter and not branched.
