Well, let's think about it as if we're painting a picture of the ecosystem. When the brown tree snakes were introduced, they had a big impact on the native species, like birds and small mammals. The balance of the ecosystem shifted, with some populations decreasing while others increased. It's like adding a new color to our painting - it changes the whole picture, but with time and care, we can work to restore harmony in the ecosystem.
Non-native species affect an ecosystem because they are organisms that are living outside of their natural range. This non-native species is a lot like pollution. It can harm or destroy native species because they compete or hunt for their food and water. Hope this helps!! :)

A keystone species is a species whose presence has a disproportionately large impact on its ecosystem compared to its abundance. If a keystone species is removed from its ecosystem, it can lead to significant changes in the ecosystem's structure and function.
Introducing a foreign species into an area is known as "invasive species introduction" or "biological invasion." This can disrupt the ecosystem by outcompeting native species for resources and causing harm to the environment and economy.
Scientists are concerned about the introduction of invasive species because these organisms can disrupt local ecosystems, outcompeting native species for resources, altering habitats, and introducing diseases. Invasive species often lack natural predators in their new environments, allowing them to proliferate unchecked. This can lead to a decline in biodiversity, negatively impacting ecosystem services and the economy. Additionally, managing and controlling invasive species can be costly and complex.
Anthropogenic changes are human-caused changes in an ecosystem. These changes can include deforestation, pollution, introduction of invasive species, and habitat destruction. Anthropogenic activities can have significant impacts on the structure and function of ecosystems.

Yes, they all can influence continual change in an ecosystem. Any of these could cause an ecosystem to spiral out of control, or could cause it to settle into a new ecosystem depending on the specifics.
The introduction of a new predator can have the species eaten with no time to evolve to defend against it
The keystone species is critical to maintaining the stability of an ecosystem, and changes in its population indicate changes in ecosystem health.
Environmental disturbances are changes in the environment that cause lasting and major changes to the ecosystem. Some examples are floods, fires, introduction of new species, windstorms, and insect outbreaks.
False. Not every change that occurs in an ecosystem is harmful. Some changes can be beneficial, such as the introduction of a new species that fills a vacant ecological niche or the restoration of a degraded habitat. However, certain changes, such as habitat destruction or pollution, can have negative effects on the ecosystem.

introduction of a new species into an ecosystem. This is an example of migration or dispersal, not evolution, as the genetic makeup of the new species remains unchanged. Evolution involves changes in the genetic composition of a population over time.
The Jamestown colonists significantly impacted the local ecosystem through deforestation and the introduction of new agricultural practices. Their need for land for tobacco cultivation led to the clearing of forests, disrupting habitats and altering the landscape. Additionally, the introduction of non-native species and livestock affected local flora and fauna, leading to shifts in the natural balance of the ecosystem. These changes contributed to soil depletion and the decline of some native species.
In 1960, an invasive species of fish, such as the common carp or the zebra mussel, was introduced into the stable ecosystem of a river. This introduction often disrupts the existing food web, outcompeting native species for resources and altering habitats. The invasive fish can lead to declines in native fish populations, changes in water quality, and overall ecological imbalance. The long-term effects can be detrimental, causing irreversible changes to the river's ecosystem.
Ecosystems can be altered through habitat destruction, introduction of invasive species, and pollution. These factors can disrupt the delicate balance of an ecosystem, leading to changes in species composition and overall ecosystem function.
