(d)How does the above food chain differ from the food chain such as:
plants → goat → man?
Humans are at the end of most of the food chains in which they occur (as this picture of man taking home a fish for food shows)Food chain - Plants → Goat → Man
In this food chain, man is at the end and he is eating the flesh of a goat.
Man is a predator here.
Food chain - Plants → Deer → Hunter (man) → Lion
In this food chain, man is not at the end of the food chain and is being eaten up by the lion.
Man is also a prey here for lions.
