1. introduction
In the heart of the rainforest, under the hidden roots of old spruce and birch trees, in the colorful coral reefs and in the midst of the diverse ecosystems of our earth, a hidden network of relationships unfolds that is as old as life itself: Symbiosis. This fascinating community of life between animals, plants, fungi and microorganisms shows that coexistence in nature is often based on reciprocity. The symbiotic relationships that species form with each other are fundamental to the survival of the biosphere and indicate a complex interaction that is the result of millions of years of evolution. By studying symbiosis, we understand not only the depth and breadth of biodiversity, but also how these relationships affect the well-being of every species, including humans.
In this article, we will dive into the world of symbiosis to explore its basics and its various forms. We will look at examples of plant-animal symbioses, from the well-known relationship between clownfish and anemone to the lesser-known connection between the orchid and its specific pollinator. You will learn about the different forms of symbiosis, such as mutualism, where both partners benefit, and endosymbiosis, where one symbiont lives inside the body of the other. In addition, we look at the important role that symbioses play in the ecosystem and take a look at the latest research and future developments in this field. Join us on this journey of discovery and learn how symbiotic relationships shape and sustain the biodiversity of our planet.
2. basics of symbiosis
Symbiosis is a fascinating phenomenon in nature in which two different types of living organisms live together and support each other. These partnerships bring benefits to both participants and are in many cases essential for their survival. Here you can find out more about the basics and different forms of symbiosis.
Definition and meaning
Symbiosis refers to a close and often long-term coexistence between two different species that is mutually beneficial. This relationship can take various forms, from occasional interactions to a profound genetic fusion. Symbiosis plays a crucial role in ecology as it helps to shape communities and supports biodiversity.
Classification of symbiosis
- Alliance/proto-cooperationThis form of symbiosis is the most relaxed relationship, in which interaction between the species occurs occasionally and is not vital. Both partners can exist independently of each other.
- MutualismIn this regular interaction, both species benefit from the relationship, although it is not essential for survival.
- EusymbiosisThis long-lasting relationship is so intense that the species involved would not be able to survive without each other. It is also known as obligate symbiosis.
Examples and applications
Symbioses can be found everywhere in nature. For example, many plants live in a symbiosis with fungi, known as mycorrhiza. This involves plants exchanging carbohydrates for nutrients and water provided by the fungus. Another example is the symbiosis between lichens, which consist of algae and fungi. The algae produce nutrients through photosynthesis, which are used by the fungi, while the fungi provide the algae with water and minerals.
These basics of symbiosis show how complex and essential these relationships are for the survival and evolution of the species involved. They illustrate the incredible interconnectedness and interdependence within the ecosystems of our planet.
3. examples of plant-animal symbioses
Symbiosis of plants, aphids and ants
Aphids are small but important players in many ecosystems, especially through their interaction with ants. These insects suck plant sap and excrete honeydew, a sugary liquid that attracts ants. Ants, in turn, protect the aphids from natural enemies such as ladybugs and other insects. This relationship is a classic example of mutualism, where both species benefit: The aphids get protection and the ants get a food source.
Hummingbirds and flowering plants
Hummingbirds play a crucial role in the pollination of many flowering plants. By visiting flowers to collect nectar, they transfer pollen from one plant to another. This interaction not only promotes plant reproduction, but also ensures the birds' food supply. The co-evolution of hummingbirds and certain flowering plants such as passion flowers, whose flower structures have adapted perfectly to the beak shapes of hummingbirds, is particularly remarkable.
Mushrooms and jungle trees
Another fascinating example of symbiosis can be found between mycorrhizal fungi and jungle trees. These fungi penetrate the roots of the trees and help them to absorb water and nutrients from the soil. In return, the fungi receive carbohydrates that the trees produce through photosynthesis. This symbiotic relationship increases the trees' resilience to environmental stressors such as drought and nutrient deficiencies, supporting the health and growth of the entire forest.
These examples illustrate the diversity and complexity of symbiotic relationships in nature and their importance for maintaining biodiversity and ecological balances.
4. different forms of symbiosis
Mutualism
Mutualism describes a reciprocal relationship in which both partners benefit. This form of symbiosis is not essential to life, but it promotes the well-being of both species. A classic example is the relationship between bees and flowers. Bees collect nectar and pollen, which serve as their food source, and at the same time contribute to the pollination of flowers. There are two main forms of mutualism: obligate and facultative mutualism. In obligate mutualism, both species depend on the relationship to survive, whereas in facultative mutualism they benefit but are not necessarily dependent on it.
Parasitism
Parasitism is a form of symbiosis in which one of the partners, the parasite, benefits while the other, the host, suffers damage. Parasites can be very specialized and often infest only a few or one specific host species. They live on or in a host organism and use its resources, which can lead to a weakening of the host. There are different types of parasites, including ectoparasites, which live on the body surface, and endoparasites, which live inside the host. Parasitoids are a special form that kill their host at the end of their life cycle.
Commensalism
Commensalism is a reciprocal relationship in which one of the partners, the commensal, receives benefits while the other suffers neither benefit nor harm. An example of this is birds removing parasites from the skin of large mammals and feeding on them. Commensalism can also be indirect, where one organism uses the resources or habitat of another without direct contact. This form of symbiosis contributes to biodiversity and structural complexity in ecosystems and can influence the behavior and ecology of other species in the community.
5. the importance of symbioses for the ecosystem
Symbiosis plays a crucial role in ecosystems by promoting biodiversity and influencing natural selection. These interactions contribute to healthy and functional ecosystems. Symbiotic relationships support biodiversity in many ways. They enable specialization and the occupation of ecological niches that would not be possible without these interactions. The close cooperation between different species creates unique communities that are essential for maintaining ecosystem functions.
Natural selection favors individuals and species that can increase their chances of survival and reproductive success through symbiotic relationships. Evolution drives the development of symbioses that are mutually beneficial and contribute to adaptation to changing environmental conditions. Interestingly, these relationships can evolve over time to become essential for the species involved, creating a co-evolutionary relationship that promotes biodiversity and ecosystem balance.
In the field of ecology, symbiosis plays an important role in shaping communities and supporting biodiversity. It is not only about the survival of species, but also about the resilience of ecosystems. As soon as a symbiotic relationship is disrupted, this can have far-reaching consequences for the entire ecosystem. In terms of biodiversity, symbiosis is crucial as it allows species to colonize new habitats and adapt to changing environmental conditions. For example, symbiosis with nitrogen-fixing bacteria enables many plants to grow in nitrogen-poor soils.
Lichens are symbioses of one or more fungi and one or more organisms that photosynthesize. These can be green algae or cyanobacteria, for example. The photosynthesis of the algae produces the sugar glucose, which the fungi can absorb and feed on. In return, the fungi release water and minerals to the algae. This can prevent them from drying out. The symbiosis between nodule bacteria and plants is extremely important for the entire plant world. The nodule bacteria are able to bind nitrogen from the air well. As there is little nitrogen in the soil, some plants take up the nitrogen they need for growth via the bacteria. In return, the host plant regulates the amount of oxygen for the bacteria and releases glucose to them.
In a coral reef, corals usually form a symbiosis with algae called zooxanthellae, which settle on the outer skin. The algae carry out photosynthesis and transfer oxygen and glucose to the coral. The algae receives vital nutrients from the coral. Mycorrhiza is the symbiosis between certain fungi and plants. The fungi are located at the root of the plant and ensure better absorption of nutrients from the soil. The plant provides glucose for the fungi to feed on.
These examples illustrate how symbiotic relationships are not only crucial for the survival of individual species, but also play a fundamental role in the stability and productivity of ecosystems.
