6 Types of interactions between biotic components in an ecosystem

An ecosystem is a complex system consisting of various components that interact with each other.

Brilio.net - An ecosystem is a complex system consisting of various components that interact with each other. One important aspect of an ecosystem is the interaction between biotic components, namely the relationship that occurs between living organisms such as plants, animals, humans, and microorganisms. This interaction plays an important role in maintaining the balance of nature and the survival of organisms. This article will discuss the various interactions between biotic components that occur in an ecosystem and how these interactions affect life.

Predation is an interaction between biotic components in which one organism (predator) preys on another organism (prey) in order to survive. A common example of predation is the interaction between lions and deer, where the lion acts as the predator and the deer as the prey. Predation helps control prey populations in nature and prevents overpopulation.

In this interaction, predators play a role in maintaining the balance of the ecosystem. For example, if the prey population is too large, natural resources such as food and water can run out, leading to starvation and environmental damage. On the other hand, a predator population that is too high can also threaten the sustainability of prey. Therefore, predation is one of the interactions between biotic components that functions to maintain harmony in the ecosystem.

Competition is an interaction between biotic components in which two or more organisms compete for limited resources such as food, water, shelter, or light. Competition can occur between the same species (intraspecific) or between different species (interspecific).

For example, two plant species may compete for sunlight in a forest. The taller plant may be able to absorb more sunlight, while the shorter plant may struggle. This competition can affect the population distribution and evolution of certain species. In the long term, species that cannot adapt to this competition may become extinct or migrate to other habitats.

Symbiosis is an interaction between biotic components that involves a close relationship between two organisms of different species. Symbiosis is divided into three types, namely mutualism, commensalism, and parasitism.

• Mutualism : Mutualism is an interaction in which both organisms involved benefit. A classic example of mutualism is the relationship between bees and flowers. Bees get nectar as a food source, while flowers are helped in the pollination process.
• Commensalism : Commensalism is an interaction between biotic components in which one organism benefits without harming or benefiting the other organism. For example, an orchid attached to a tree trunk. The orchid gets a place to grow, but the tree does not benefit or suffer from the presence of the orchid.
• Parasitism : Parasitism is an interaction in which one organism (the parasite) benefits, while another organism (the host) is harmed. An example is fleas that live on the body of an animal. The fleas draw blood from the animal, while the host suffers from blood loss or skin irritation.

Herbivory is an interaction between biotic components in which herbivorous animals consume plants as a source of food. In this interaction, animals such as deer, cows, or rabbits eat parts of plants such as leaves, stems, or fruits. Herbivory is an important part of the food chain because the plants eaten by herbivorous animals will later become a source of energy for carnivorous animals that prey on the herbivores.

Herbivory can affect the growth and development of plants. Plants that are frequently eaten by herbivores often develop certain adaptations, such as spines or poisons, to protect themselves from herbivore attacks. This is one example of an interaction between biotic components that shows how plants and animals influence each other.

Amensalism is an interaction between biotic components in which one organism suffers a loss, while the other organism does not benefit or suffer a loss. An example of amensalism can be seen in large trees growing in a forest. These large trees can block sunlight from reaching small plants below them, making it difficult for the small plants to grow, even though the large tree does not benefit or suffer a loss from this situation.

Amensalism often occurs in dense ecosystems where resources such as light, water, and nutrients are limited. This interaction emphasizes the importance of the environment in shaping patterns of interaction between organisms.

Neutralism is an interaction between biotic components in which two organisms live side by side without affecting each other. In complex ecosystems, neutralism is a common type of interaction, especially between organisms at different trophic levels. For example, the relationship between a deer grazing and a bird flying overhead. The two organisms do not affect each other in terms of benefits or harms.

Neutralism shows that not all interactions in an ecosystem are competitive or beneficial. In many cases, organisms can live together without significantly affecting each other.

Changes in one component of an ecosystem can affect the entire structure of interactions between biotic components, so maintaining a healthy ecosystem is a priority in efforts to preserve the environment and biodiversity.
