URGENT PLS HELP! What are trophic levels? Be able to identify and label decomposers, primary producers, primary consumers, secondary consumers, and tertiary consumers

The trophic levels are producers(primary), herbivores (primary consumers), carnivores or omnivores(secondary), and usually carnivores for tertiary.

Explanation:

Decomposers (fungi) eat dead things, producers are plants, whoever eats plants are primary consumers (bug), whoever eats them are secondary (bird), whoever eats secondary is tertiary (fox).

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
