Which of the following animals indicated in the antarctica food web folder is a source of food for the greatest number of other animals in this food web?
a. fish
b. phytoplankton
c. killer
d. whales
e. krill squid

B. Phytoplankton

Explanation:

In the antarctic, the basic source of food is the phytoplanktons which are autotrophic and self-feeding organisms of the plankton community and these play a key role in the ocean, the sea, and the freshwater and they comprise of the tiny individual member and have a global biomass of 1%. They are rich with vitamin B, and they at times can mead to the acidification of the oceans when increase in numbers thus needs to be taken care of hence they are eaten by the shrimp population and they then contribute to the increase n the population of the bigger fish i.e the whales and thus forms the basic source of the food web.  These phytoplanktons are also known as the producer if the antarctic food chain.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
