B) only II Plants are called primary producers because they produce the material and store the energy at the bottom of the food chain. In turn, zooplankton, which include copepods, jellyfish and fish at the larval stage, provide food for filter-feeding organisms such as bivalves and sponges as well as amphipods, other fish larvae and small fish. Like their aquatic counterparts, they use photosynthesis to convert nutrients and organic materials from the soil into food sources to nourish other plants and animals. Analysts at Deutsche Bank raised their target price on Associated British Foods from 2,180.0p to 2,300.0p on Tuesday, stating its Primark unit had driven "another upgrade".

Choose ONE of the following prompts :Prompt 1: Using at least 5 sentences, explain the difference between primary and secondary succession. Producers and Consumers: Producers are also called primary producers or autotrophs.

For most terrestrial ecosystems, pyramids composed of species abundances, biomass, and energy are similar in that they have a broad base and a narrow top. Primary consumers are those organisms which feeds on producers. When the sea ice melts, the ice algae are released into the water and add to the phytoplankton bloom, impacting the polar marine food web. Higher levels of phytoplankton, likely due to greater availability of nutrients and longer residence time have been found in marsh systems than in nearby coastal estuaries.
