The place an organism attains in a food web is called its trophic level. There is a maximum of three to four trophic levels in a food chain. The first level is producers, the second level is primary consumers, the third level is secondary consumers, and the fourth level is tertiary consumers.

In the environment, cyanobacteria are identified asthe most significant primary producers. Phytoplankton includes cyanobacteria, also known as blue-green algae. They are the leading producers in the sea.

Thus, 鈥榗yanobacterium鈥� and 鈥榩rimary producer鈥� are correctly paired.

Therefore, the given option is incorrect.

Grasshoppers are the main consumers because they consume the producers, which are plants or grass. As they eat grass, they are one trophic level higher than grass and are primary consumers, which is the second trophic level.

Thus, 鈥榞rasshoppers鈥� and 鈥榩rimary consumers鈥� are correctly paired.

Therefore, the given option is incorrect.

Zooplankton is the principal consumer at the bottom of the aquatic food web; hence, they feed on phytoplankton, which obtains their energy directly from the sun.

Thus, 鈥榸ooplankton鈥� is incorrectly paired with 鈥榩rimary producer鈥�.

Therefore, the given option is correct.

Detritivores are types of decomposers. Animals that break down and devour dead or rotting stuff are known as decomposers. In the forest, fungi eat the decaying matter. Thus, fungi are decomposers.

Thus, 鈥榝ungi鈥� is correctly paired with 鈥榙etritivores鈥�.

Therefore, the given option is incorrect.
