The producers can be described as organisms which are able to make their own food through the process of photosynthesis. Phytoplankton is hence the producers in this food chain.
Primary consumers can be described as organisms which feed on the producers. Copepods are the primary consumers in this food chain.
Secondary consumers can be described as organisms which feed on the primary consumers in a food chain or food web. Sea-nettle jellyfish is the secondary consumer in the above food chain.
Replication is involved in duplicating and copying genetic material. DNA strands serve as templates during DNA synthesis. Thus, option c is correct.
In DNA replication, the parent strand act as the template strand and is used by DNA polymerase to make the copy by attaching the complementary bases.
The daughter strand formed is semi-conservative in nature. The parent strand acting as template results in leading and lagging strands.
Therefore, the DNA strand act as a template.
