Are there dominant species in a diverse ecosystem?
In a diverse ecosystem, there may be certain species that are more abundant or have a greater impact on the ecosystem than others. These species are often called dominant species. Dominant species can influence the structure and function of the ecosystem by outcompeting other species for resources or by providing key ecosystem services.
Ecosystem boundaries are usually defined by easily identifiable demarcations?
Ecosystem boundaries are often defined by physical features such as rivers, mountains, or coastlines. These features can act as barriers that limit the movement of species and resources in and out of the ecosystem. Additionally, human activities can also influence and alter ecosystem boundaries.
What is found in the single plant community?
A single plant community typically consists of only one dominant plant species that thrives in a specific habitat. This type of community is characterized by a homogenous vegetation structure and composition, with the dominant species playing a key role in shaping the ecosystem dynamics and functioning. The presence of other plant species within this community is usually limited, with the dominant species outcompeting other plants for resources such as sunlight, water, and nutrients.
Introduced species often take over an ecosystem because they usually what?
Introducing new species threatens biodiversity in several ways. The new species may upset the food chain in an area. If a species grows faster than native species, they may eat all of the food, leaving little for the natural fauna. The new species may also, conversely, be great food for an existing species which would give one species a great growth advantage over others.
When do species compete in an ecosystem?
Since food and other resources are limited, the members of a species must compete with each other to survive. Competition does not always involve direct physical fights between members of a species. Instead, competition is usually indirect.

Plants introduced into new habitats in which they were not originally raised are?
Invasive species are different species, either plants or animals, which are purposefully or accidentally introduced into a new ecosystem. They can be good in some ways but bad in others because they usually don't have as many predators in the new ecosystem and can take over.
What is a primary species?
A primary species is a species that occupies the first trophic level in an ecosystem. These species are usually autotrophs, such as plants, that convert sunlight into energy through photosynthesis, forming the base of the food chain. They are vital in supporting the rest of the ecosystem by providing energy and nutrients for other organisms.
What is keystone species?
Keystone species are those which play a major role in determining which species exist in a particularcommunity. They are critical factors in ecological processes such as energy flow and nutrient cycling.If we can identify a keystone species and quantify its impact on its community then we can usually understand how the community functions as a whole. The importance of these species is such that their loss from a community may bring about a cascade of other species extinctions. Often a keystone species is not recognised until it is wiped out and many other species which were dependant upon it disappear also.
What are two examples of species that are endangered because something in their ecosystem with was disturbed?
Flightless birds in the pacific are usually endangered or extinct, they can't compete with European mammals, such as cats, foxes and dogs. The disturbance usually being the introduction of a new species. The kiwis of New Zealand is one example Different species of Wallaby is another.
How does tigers fit into an ecosystem?
Tigers play a key role as top predators in their ecosystem, regulating prey populations and maintaining the balance of species. By controlling herbivore numbers, tigers help to prevent overgrazing and protect the habitats of other species. Their presence contributes to the overall health and diversity of the ecosystem.
True or false when non native species enter an ecosystem they usually occupy unfilled niches?
True. Non-native species often fill ecological niches in new ecosystems because they are not in direct competition with native species for resources. This can lead to displacement or extinction of native species.
Is a tree harmed because of the presence of birds?
Usually no.
What is the physical difference between a healthy freshwater ecosystem and an unhealthy freshwater ecosystem?
Appearance is not an accurate indication of potability [ drinkability -- fit for human consumption ]. For example, a powerful poison can be a clear, transparent and sparkling liquid in a glass, looking exactly like a glass of refreshing water. But what a difference healthwise !!! The above answer does not tell much about the health of an ecosystem, although it is important to remember when looking for a source of drinkable water. A healthy freshwater ecosystem will have little pollution, few invasive species, and an abundance of both plant and animal species. The presence of leeches usually indicates good quality water.
How does the energy leaves the ecosystem?
Usually, energy leaves the ecosystem when an organism leaves the ecosystem, they usually leave by death.
Ecosystem boundaries are usually defined by easily identifiable demarcations?
Ecosystem boundaries are often defined by physical features such as rivers, mountains, or coastlines. These features can act as barriers that limit the movement of species and resources in and out of the ecosystem. Additionally, human activities can also influence and alter ecosystem boundaries.
