Ecosystem: a stable natural system with a closed circulation of substances between living and non-living components

An ecosystem is a complex and stable natural system in which living and nonliving components interact with each other, forming a closed cycle of substances. In an ecosystem, each element has its place and performs its function, which allows it to maintain balance and continue to exist.

One of the main components of an ecosystem are living organisms such as animals, plants, fungi and microorganisms. They perform a number of important functions such as photosynthesis, respiration and the decomposition of organic matter. Living organisms also serve as a source of food for other living things in the ecosystem.

Nonliving components of the ecosystem also play an important role. These include water, soil, rocks, atmosphere and other natural resources. Nonliving components provide living organisms with the necessary conditions for life and growth, such as water, minerals and light. They also provide habitat for many living organisms.

In an ecosystem, all components interact with each other, forming a complex network of connections. For example, plants absorb carbon dioxide from the atmosphere and produce oxygen, which is necessary for animal respiration. Animals, in turn, absorb oxygen and release carbon dioxide, which is used by plants in the process of photosynthesis. Some living organisms are also important dispersers of pollen and seeds, which contribute to the diversity of plant cover in an ecosystem.

However, the ecosystem can be disrupted by external factors such as air and water pollution, deforestation, climate change and others. This can lead to an imbalance in the ecosystem and even its complete destruction. Therefore, it is important to keep the ecosystem in its natural state and take measures to protect and restore it.

In conclusion, an ecosystem is a stable and complex natural system in which living and nonliving components interact with each other, forming a closed cycle of substances. The ecosystem plays an important role in maintaining life on Earth, so its protection and conservation are the tasks of all humanity.

An ecosystem is a community of living organisms interacting with each other and with their environment. Ecosystems can vary in size from microscopic to global. Within an ecosystem, there is constant interaction between various components such as plants, animals, microorganisms and other elements.

Ecosystems have a complex structure and structure. They include several layers, each of which performs its own functions. For example, the top layer, made up of plants, provides food and energy for other components of the ecosystem. The bottom layer consists of microorganisms that process waste and produce nutrients. Between these layers are animals and microorganisms that play their role in the circulation of substances and energy.

There are different types of connections in an ecosystem. Interaction between living organisms occurs through food and trophic chains, as well as through the transfer of genetic information. In addition, the mutual influence of species and communities can lead to changes in the characteristics of the ecosystem and even its destruction. Disruption of the balance in the ecosystem can lead to environmental disaster.

The destruction of ecosystems can be caused by a variety of reasons, including human activity. For example, deforestation leads to a decrease in the area occupied by forests and other plants. The construction of dams and dams changes the flow of water, which leads to shallowing of rivers and lakes. Increase in animal numbers
