<span>Agar
is known to be a gelatinous polymer substance that was commonly used in the
laboratory setting as a substrate. Thus, nutrients agar can grow different types
of microbes such as fungi and bacteria while MacConkey agar is made with bile
salts and crystal violets, these additives cause the agar to only grow Gram –
negative bacteria. However, nutrients agars grow more organisms because it
contains nutrients from either beef broth or yeast extracts when compared with MacConkey

A swamp is an area of a land that is permanently filled with water. It could be formed out from a former lake or pond overtaken by trees. It is also dominated by trees. Cypress and tupelo trees, bushes and shrubs grow in swamps and even tiny plants like the duckweed that almost covers the water surface.

This protein is broken down by a number of enzymes and converted into amino acids which is used in the growth of the body, formation and repairing of muscles.
Answer:
Explanation:
The near-surface open water surrounded by the littoral zone is the limnetic zone. The limnetic zone is well-lighted (like the littoral zone) and is dominated by plankton, both phytoplankton and zooplankton. Plankton are small organisms that play a crucial role in the food chain.
