Decomposers, as the name suggests, decompose dead plants or animals into simple compounds. They feed on dead producers from the first levels or consumers from other three levels. Breaking them down, decomposers release nutrients that producers can use.
In an ecosystem with four levels, the first level are producers, such as plants and algae. On the second trophic level, there are primary consumers, herbivores that eat plants, for example, a deer, a rabbit, a grasshopper. The next trophic level belongs to secondary consumers that eat herbivores, for example, a wolf, a fox. The highest level is tertiary consumers that eat carnivores, for example, a bear, an eagle.
the second one i’m pretty sure
Answer:
A. A prokaryote lacks a well-defined nucleus.
C. A prokaryote lacks cell organelles.
Explanation:
A prokaryote has DNA or RNA just floating in the cytoplasm. There is no nucleus to hold them inside. A prokaryote also lacks a mitochondria and other organelles, so it is different from a eukaryote.
Answer:
The flowchart that identifies an animal as herbivore or carnivore is attached as an image and discussed as follows:
Explanation:
Suppose we have two animals an elephant and a lion, now the flow chart for the elephant would be as follows:
start -- Read the name of the animal (elephant) -- Does it eat only plants?---Yes--Print Herbivore-- end
Now, the flowchart for the lion would be as follows:
start -- Read the name of the animal (lion)--Does it eat only plants?---No---Print Carnivore-- end
Thus, these are two examples given above to make a flowchart to find and classify an animal as herbivore or carnivore.

Not all rainforests are tropical rainforests because some are distinguishable from the others and these rainforests has its own designated climate that allows the specific species of plants to grow and thrive in that environment.
