Transcript of The Importance of Interaction in Ecosystem

The Importance of Interaction in Ecosystem
The Meaning of Biodiversity
Biodiversity is the presence of a large variety of plants and animals in the environment. Biological interaction is the interaction between living organisms and the environment. There are various types of biological interactions such as prey-predator, commensalism, mutualism, parasitism, and competition. There are many reasons on why biological interaction is important.
Importance of Interaction in Ecosystem
One of the importances of biological interaction is that it maintains the food web. A food web shows the food relationship among living organisms and most food webs start with green plants. An example of a food web is that of grass eaten by a grasshopper, a grasshopper eaten by a frog, a frog eaten by a snake and an owl. If biological interaction doesn’t exist, many animals would die from starvation as the food web wouldn’t exist.
Secondly, another reason on why biological interaction is important is because it controls the population of living organisms. A predator is a living organism that hunts other living organisms for food and a prey is a living organism that is hunted by predators. For example, a lion is a predator and a zebra is its prey. The population of living organisms would be overloaded if biological interaction didn’t exist.
Thirdly, the importance of biological interaction is it allows the living organisms to protect each other. This can be shown by mutualism which is an interaction between two different species of living organisms in which both parties benefit. A fungus and an alga live closely together to form a lichen, together the fungus and the alga are able to survive in harsh environments where neither organism would be able to live on its own. Many living organisms would be destroyed if biological interaction didn’t exist.
Finally, another reason on why biological interaction is important is because it provides the Earth with natural resources. For example, the process of photosynthesis by green plants releases oxygen which is inhaled by animals and humans. Another example would be when an animal defecates, its faeces would be used by plants as fertilizers. These natural resources are important as they play a role in maintaining the balance of nature and they would seize to exist if biological interaction didn’t exist.
Conclusion
These reasons prove that biological interaction, which is the interaction between living organisms and the environment, is important.
