Importance of Eco System

aquatic ecosystems



An ecosystem is generally a community of plants, animals or small organism that live, feed, reproduce and interact in the same area or environment, some can be very large while others may be physically small.

This environment supplies materials and energy, requirements and provides living conditions to organism communities. Now an organism community is considered a biological community living within the non-living environment given the term an ecosystem. An ecosystem can be natural or artificial, permanent or temporary which can be either coral reef, pond, grassland or a village.

While, the name given to the study of an ecosystem is called ecology, or how living things relate within their  environment and to one another. In order to truly appreciate the ecosystem we must understanding this relationship which is vitally important because living things and non-living things depend upon and impact on each other, specifically for survival.

The ecosystem is a dynamic system that includes, a biotic component and abiotic environment influencing the properties of each other and both necessary for maintenance of life. The two (2) main components of the ecosystem are:

Biotic means living, and biotic factors are the other, living parts of the ecosystem with which an organism must interact. The biotic factors with which an organism interacts depend on whether it is a producer, a consumer, or a decomposer, but nevertheless these include water, fish, plant and microorganism.

Environment of an ecosystem 


While, the abiotic factors are chemical and physical factors such as temperature, soil composition, and climate, along with the amount of sunlight, salinity, and pH. These includes air, carbon dioxide, oxygen, soil (nutrients), water and sunlight.

These two factors are connected to each other like how the river is connected to the ocean, however human behaviors may affect and modify natural ecosystem into man-made or anthropogenic ecosystems lets take for example a forest which is an important aspect of an ecosystem since it provides food and shelter for juvenile animals are being cut down and turned into tree planting and agricultural systems.

It is worth noting that there exits two overall categories of the ecosystem in nature terrestrial and aquatic, these two aspects of the ecosystem are very different and unique and are not very easy to compare or define because of the variety existing within, discussed here-under.

  • Terrestrial ecosystem – is a community of organisms and their environment that is found on land this type of ecosystem includes tundra, taiga, deciduous forest, grasslands, tropical rain-forest and deserts.

Terrestrial ecosystems are characterized by greater temperature fluctuations on both and seasonal basis than those occurring in an aquatic ecosystems in similar climates. The availability of light is greater in terrestrial ecosystems than in aquatic ecosystems because the atmosphere is more transparent in land than in water, also gases are more available in terrestrial ecosystems such as carbon dioxide this is critical for the processes of photosynthesis, which gases are obtained and where the physical energy of light is transformed into the organic energy of carbon-carbon bonds through the process of photosynthesis.

Terrestrial Ecosystem 


  • Aquatic ecosystem – is an ecosystems in a body of water, these are divided into two main areas marine and freshwater ecosystems. Aquatic environment are very stable as compared to the terrestrial environment, with smaller fluctuations in temperature and other variables, light and oxygen are limiting factors in the aquatic ecosystem.

Water supply is closely related to the aquatic ecosystems and ecosystem sustainability in an overall sense. Nature has a well orchestrated system and a unique and powerful mechanism to perform its function in what we can refer to as a balancing act for the overall benefit of all living things, but in the aquatic ecosystem one of its most important roles is to act as a giant water filter and as a means of re-charging reserves of resources that are necessary for life.

Aquatic Ecosystem 


In other words, if we protect existing natural habitats, we will help to maintain biodiversity, unfortunately, natural habitats and their ecosystems although so precious are more and more endangered because of the damaging environmental effects of growing human populations everywhere and all of our activities.

It is very important to understand and appreciate the way the ecosystem work, in order for us as citizens of this planet to develop knowledge about how to protect and preserve the ecosystem by developing and implementing the appropriate management structures.

One thought on “Importance of Eco System

  1. […] The biotic components of an ecosystem are the life forms that inhabit it. The life forms of an ecosystem aid in the transfer and cycle of energy. They are grouped in terms of the means they use to get energy. Producers such as plants produce their own energy without consuming other life forms; plants gain their energy from conducting photosynthesis via sunlight. Consumers exist on the next level of the food chain. There are three main types of consumers: herbivores, carnivores and omnivores. Herbivores feed on plants, carnivores get their food by eating other carnivores or herbivores, and omnivores can digest both plant and animal tissue, see more information in my previous post importance of the ecosystem here.
