Hello everyone, I hope you find today post interesting. But before we get all scientific and stuff; I am very much concern about human treatment of the environment. Humans need the environment more than the environment needs us. It provides us with clothing, food, shelter, knowledge and medicine. But we still continue to exploit the environment in an unsustainable manner. We all know the consequences of our actions, but we turn a blind eye. What will we do when new hybrid diseases, famine, mega storms and mass flooding are at our doorsteps? There must be a hidden agenda or force influencing unsustainable development. If that’s not the case then humans can be rated as one of the most ignorant species on the planet.
Level of Ecosystem
Ecosystems vary in size and also conditions usually differ from ecosystems to ecosystems. An ecosystem can be small such as under a stone or even large as in the case with the Amazon Rainforest.
Listed below are the levels of ecosystem:
- Micro – E.g. water droplet and under a leaf
- Meso – E.g. wetlands and sand dunes
- Global (biome) – E.g. Tropical rainforest and tundra
Spatial distribution refer to something being arrange, spread or scatter over a range/ area. Ecosystem have boundary in which all its component function together. A lot of times the spatial boundaries of ecosystems do not conform to political boundaries (borders of countries). The Amazon Rainforest is a good example of ecosystem spatial boundary not coinciding with political boundaries.
Types of Ecosystems
Temporary (e.g. pond fed by rainfall) or permanent (e.g. ocean), natural (e.g. forest) or artificial (e.g. farm) and Aquatic (e.g. river, lakes, ocean, etc.) or terrestrial (e.g. valleys, mountains, plains, tundra, etc.). In general, ecosystems are either natural or artificial. Artificial ecosystems refers to cities, farms, zoos, etc. Natural ecosystems can either be aquatic or terrestrial. Aquatic is the term used to refer to ecosystems composing of water. And “terrestrial” is the term used to refer to ecosystems made-up of land. Aquatic ecosystems can either be freshwater or marine. Freshwater ecosystem can either be Lentic or Lotic and marine ecosystem can either be ocean or seas.
Relationship in Ecosystem
Relationship in ecosystem can either be:
- Predator/Prey (Predator Video)
- Competition: It describes the act of two organisms or species compete for resources.
- Symbiosis: Relationship developed by different species living in close association with each other (Symbiosis Video).
- Commensalism: This is when one organism benefit and the other is not affected.
- Mutualism : Both organisms benefit
- Parasitism: This is when one organism benefit and the other is harmed as a result.
