Which of the following statements about plankton or nekton is NOT correct?
Oduvanchick [21]

Answer:

C. All plankton are closely related to plants.

Explanation:

Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.

Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.

Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.

Nekton are organisms found in water that swim actively.

Based on this information, we can conclude that statement C is the only incorrect statement.

bogdanovich [222]

Answer:

I think this is the list right? - Felis catus Sylvilagus audubonii Parus inornatus Euarctos americanus

Explanation:

When two members of the same species (male and female) mate, they produce fertile offspring.

The conclusion that can be drawn from this is that due to the fact that from looking at the scientific names of the animals, there are different genus and species names, there would be no interbreeding between them as they do not belong to the same species.

And if peradventure there is crossbreeding, the union would be unable to produce fertile offspring.
