Interpretation: A food chain which showing the link between plankton and humans has to be constructed and the impact of ocean acidification on this food chain should be explained.
Concept Introduction:
A food chain is a series of events in which one organism eats another and obtains energy and also it is one of possible representation of a path along which energy can move through an ecosystem.
A food chain consists,
- (i) Producer
- (ii) Consumers
- (iii) Decomposer
Planktons are any floating or drifting organisms having size range relatively small and microscopic or sometimes large, including both plants and animals which live suspended in the water column of seas, lakes, ponds and rivers…
Phytoplankton is the primary link of the marine food web and it is the source of almost 50 % of our oxygen.
Zooplanktons are the source of food for larger animals like whales and it is the consumer in the marine food chain. Zooplanktons are the intermediate link that transfers energy captured by phytoplankton to these animals.

- Soap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups.
