Explanation:
The answer is c in my understanding
The source is the allele for beak size being different, or more specifically the DNA sequences being different.
Walleye like to eat minnows. In turn, the minnows feed on scuds (zooplankton) which eat algae (phytoplankton). In this system, the zooplankton are the primary consumer.
Zooplankton is animal plankton that is bigger in size than phytoplankton. The zooplankton is made out of both primary consumers which eat free-drifting algae, and secondary consumers, which feed on other zooplankton. These creatures are consumers since they should eat preformed organic compounds to endure in the ecosystem. Thusly, zooplankton then becomes nourishment for a bigger, secondary consumer like fish. Zooplankton incorporates microscopic and macroscopic life organisms and is of various kinds, and their food sources are vary extensively.

D. Bacteria
Nitrogen-fixing bacteria found in both the soil and root nodules of leguminous plants fix nitrogen into a form that can be used by plants.
The water level in the bucket would drop.
This is because the pebbles have a greater density than water - they displace more water (when floating in a cup), than their volume. Thus the water displaced by the cup of floating pebbles has to be more than the volume of pebbles in the cup.
