that kingdom would belong to the primary producers also known as autotrophs (they produce their own resource) as they are single celled organism (as we are too) that have a nucleus and a cell wall that is contained of cellulose that only plants, algae, and fungi could have, it provides protection for the cell. and the chloroplast are only in photosynthetic organism which are plants (and some other creatures like some bacteria and protists) where they take light energy from the sun into usable chemical energy.

Krill in this food web is the primary consumer. Since the producer of the food web is the phytoplankton. Removing them from the food chain cuts the supply of food for secondary consumers such as seals, and whales. This disrupts the whole Antartic ecosystem since there will be a large amount of phytoplankton but not enough food for secondary consumers. This because secondary consumers are not able to eat phytoplankton due to their microscopic size. Only krill are able to feed on them and have the maximum energy gain from them.
So it's easier to understand how plants take in carbon-dioxide and how much carbon-dioxide is in the atmosphere
