Question

basic knowledge in this area. Part A Suppose that 60% of Earth's species became extinct during a mass extinction. If you could survey Earth's biological communities 10,000 years after the end of this mass extinction, which of the following would you most expect to find? Net primary production (NPP) would be higher than before the extinction. e Food webs would show fewer connections and fewer trophic levels than before the extinction. Species that were well adapted to conditions before the extinction would have survived. The number of species would have recovered to pre-extinction levels.

Answer 1

The answer is b. Food webs would show fewer connections and fewer trophic levels than before the extinction.

Reason:

There must be more food available from the lower level to ensure energy is available everytime when an organism of a higher trophic level ingests food inreases as you go up in the food chain.

Also remember the number of organism decreases considerably at each level in the food chain.

so the Food webs would show fewer connections and fewer trophic levels than before the extinction.
