Multiple choices :
A. test for chemicals that might poison fish and cause algae to grow
B measure the dissolved oxygen content in pond-water samples
C look for sources of pollution that may be affecting the pond
D measure the amount of light at various levels in the pond
Answer;
D. measure the amount of light at various levels in the pond
Fish in the pond feeds on the algae that grows in the pod.

Answer:
The only living characteristic of viruses are that they reproduce but only inside the host body, using its machinery they can mutate and change over time. In the case of retroviruses, DNA can be passed to succeeding generations.
the non living characteristics of viruses include that they are not cells; they lack plasma membrane, cytoplasm and cellular organelles and they can not undergo metabolism. they can not maintain homeostasis as they crystallize out of the host body. they can not grow, just multiply using the host machinery.
considering some facts that viruses can reproduce inside hosts body, and that they can mutate we can say that they are living.
but flipping the coin, viruses are not cells, they lack cytoplasm and organelles and they crystallize out of the host body. We can say that they are non-living.
but up till now biologists place viruses on a border line of living and non living.
