Answer:The correct answer is
Sun → Maple trees → Caterpillars → Finches → Hawks
Sun → Grass → Cows
Sun → Plankton → Shrimps → Salmon fish → Humans.
Explanation:
In the given questions, examples shown create food chains in an ecosystem.
A food chain is a directional flow of energy and matter in the form of food an organism eats which could be terrestrial or aquatic.
A terrestrial food chain starts with autotrophs or producers like maple trees, grass which can produce their own food and present at the lowest trophic levels. These autotrophs are eaten by herbivores such as caterpillars which feed on the leaves of maple trees and cows which eats grass and are known as primary producers. Further carnivores like finches feed on these caterpillars which can be further eaten by higher carnivores like hawks.
An aquatic food chain starts with plankton which can be eaten by shrimps on which salmon fish can feed and these fishes are further eaten by top carnivores like humans.
Thus, these selected examples make food chains in an ecosystem.
