Living things develop and change over millions of years. During this process, ecological effects occur and may harm the environment. Ranging from wildlife and fish to forest decline, the standard functionality of an ecosystem might change as a result of evolution and ecological effects. This section will outline the results of toxic substances, pesticides, and other forms of pollution.
What is Ecology and Evolution?
Organisms (biota), along with the physical environment, inhabit a place and make up the ecosystem. Some typical examples of the ecosystem are a rain-forest, farm pond, and mountain meadow. The ecosystem follows a process over the years. Examples include birth, growth, reproduction, and the death of biota in that particular environment.
In this process, many effects occur in the surroundings, and energy gets recycled and flows through the entire process. Therefore, species that better adapt come to dominate in that environment or the altered and new ecosystem.
The Organization of the Ecosystem
Ecology and evolution are concerned with how individuals interact with each other and the environment. Also, communities comprise of different populations of micro-organisms, animals, and plants. Therefore, populations of different species tend to interact more than with those of the same species.
Within a defined physical space, you will identify different communities of organisms. As such, the forest consists of plants, animals, the forest canopy, soil, and water. In this ecosystem, evolution takes place and results in identified effects.
Ecosystem and its Adverse Effects
As an ecosystem undergoes natural forces, it continues to be the same ecosystem. For instance, a pond ecosystem might experience floods but remains a pond. The resilience of an ecosystem enables its quick recovery and resists changes.
On the other hand, non-natural phenomena and toxic pollutants can cause instability in an ecosystem and massive losses as illustrated below:
• Air pollution and acid deposits decimate forests
• Death of invertebrates such as fish
• Timber growth decline
• Loss of commercially treasured and endangered species
