<span> Cell Walls – Bacteria (prokaryotes of the domain Eubactera) have cell walls that contain the molecule peptidoglycan. No other type of organism has a cell wall containing this molecule. Prokaryotes in the domain Archea have cell walls, but they are made of materials other than peptidoglycan. Eukaytotic animal cells do not have cell walls. Eukaryotic plants and fungi have cells walls, made of cellulose and chitin, respectively. </span>

The given question is incomplete as there is no food chain given in the question, but based on the knowledge it can be said so that producers are present in abundant amount in every food chain.
Answer: Producers
Explanation:
The producers can be defined as the organism which have the ability to make food. This food is used by the other organism of the food chain as a soul source of energy.
They are huge in number so that they can produce enough food to meet the requirement of other organisms. Though all of the organisms are not directly dependent on producers ,some of them(carnivores) are also dependent on the organism eating plants(herbivores).
Producers→ primary consumers(herbivores)→ secondary consumers(carnivores)→tertiary consumers(carnivores).
Here, we can see that the all the organism are directly or indirectly dependent on the producers and they are abundant in every food chain.
Regrowth of grasses, ferns, wildflowers, and saplings after a forest fire is an example of secondary succession.
Secondary succession is one of the two main forms of ecological succession of plant life that is initiated by an occurrence such as harvesting, or forest fire, that has a negative impact or diminishes an already established ecosystem such as a forest or a wheat field to a lower number of species. Several factors such as initial composition, trophic interaction, and competition-colonization trade-offs can influence secondary succession.
