What is a Primary School Ecosystem?
An ecosystem is a whole made up of an environment and the living beings that inhabit it. ... In the same ecosystem, different living beings interact with each other: predators hunt their prey while other living beings live in symbiosis (they cannot live without each other).
It is a community of living organisms of different species that live in a particular place (biocenesis or biotic component) and physical environment (biotope). Relationships are grafted between the organisms of an ecosystem and the environment that give rise to a continuous exchange of matter and energy.
An ecosystem is a systemic whole (often called "ecological unit") made up of two closely related components: the first represented by living organisms (biological community or biocenosis) and the other by the physical environment (component abiotic) in which they live .
This set of natural elements and life forms that each exist in relation to the others is called the ecosystem! Each ecosystem has its own characteristics, but there are some fundamental factors that determine the environment and the consequent forms of life that we will find within it.
The physical place where the environmental factors themselves allow the survival of a species is defined as habitat, while the conceptual space delineated by all the environmental factors and by all the interactions, biotic and abiotic that influence the existence of a species in an ecosystem goes to constitute a niche ...
Levels of biological organization Ecosystem: it is a naturally delimited portion of the biosphere, in which animal and plant organisms interact with each other and with the surrounding environment (biotope). Biocenosis: the community of species of an ecosystem that lives in a given environment (biotope).
On Earth there are different types of ecosystems: a first major distinction can be made between natural and artificial ecosystems .... Natural ecosystems
- The forest (temperate, tropical and boreal);
- The savannah;
- The steppe;
- The desert;
- The tundra;
- The Mediterranean scrub.
A food web is made up of many food chains that are intertwined with each other. If an animal of the food web disappears, there can be danger for all the others, because they could starve or reproduce enormously, as they are no longer eaten by tertiary consumers.
In some biotopes we find a set of specific and particular characteristics, not easily reproducible elsewhere. In such cases, the biotope can be of particular importance as it can represent the only place where native species live.
The abiotic factors are identified with the characteristics of the environment and which have no relation to the presence of living beings. Biotic factors, on the other hand, are made up of living organisms that are present in the environment and the relationships between them.
