The commercial fishing industry uses large nets to capture fish. Often these nets catch many species of organism that are not used by humans. What Change could lessen the negative effect to this practice for the commercial fishing industry? A. Designing nets that release unwanted species without harming them.

B. Using the net in deeper regions of the ocean where different organisms live.

C. Decreasing the size of the nets, but using more of them.

D. Exploring new and uncharted areas of the ocean where the nets can be used.

A. Designing nets that release unwanted species without harming them.

Explanation:

Over-fishing is a negative human practice that leads to the over-exploitation of aquatic ecosystems (i.e., both marine ecosystems and freshwater ecosystems). In an aquatic ecosystem, the communities of organisms coexist in a delicate balance where they are dependent on each other in the food web, providing stability to the whole ecosystem. Therefore, the over-exploitation of any aquatic species is expected to impact the whole ecosystem, thereby also having a negative impact on other fish populations.

the answer is: trichonympha lives in the gut of termites and digests cellulose eaten by the termite.

this is an example of a symbiotic association of a protozoan with its mode of association.
