The answer is B and D i learned this in biology last week
Answer:
B
Explanation:
Answer B is correct:
Because the biologists are continuing to learn more and more about such minute organisms, protozoan systematics – that is, the taxonomy (classification) and the evolutionary interrelationships of major groups of protozoa – remains a topic of debate and change, still today.
Some of the rather LARGE and unwieldy taxonomic groupings of past years are particularly subject to revision with expansion of and refinement in the knowledge about the members of those – and related – assemblages. Paradoxically, the protozoa themselves are becoming more difficult to define with precision as our information about them and other microbial assemblages increases. Thus, presenting a single satisfactory circumscribed definition for them is not an easy task.
...
Answer A sounds so funny.
Answer C and D are false because Protozoans are usually single-celled and heterotrophic.

Hope this answer can help you. Have a nice day!
Answer:
In the food chain, producer makes the base, primary and secondary consumers are present in the middle and tertiary consumers is present on the top.
Explanation:
Producers are the organisms which makes their own food such as plants. They are placed at the base due to high population. Primary and secondary consumers are placed in the middle due to less population than producer and tertiary consumers are placed on the top due to very low population.
