Which is an biotic change in an ecosystem?
A biotic change in an ecosystem refers to alterations caused by living organisms, such as the introduction or extinction of a species. For example, the arrival of an invasive species can disrupt existing food chains and lead to declines in native populations. Additionally, changes in species interactions, such as predator-prey dynamics, can significantly impact the structure and function of the ecosystem. Overall, biotic changes can affect biodiversity and ecosystem stability.
What happens to the ecosystem when a predator species is extint?
Typically, the species that it ate overpopulate, and the ecosystem is disrupted.
What are some possible impacts of adding or removing a species from an ecosystem?
Adding a species can disrupt the balance of the ecosystem, leading to competition for resources and potential changes in the food chain. Removing a species can also have cascading effects, such as disrupting predator-prey relationships or altering nutrient cycling processes. Both scenarios can result in changes to biodiversity and overall ecosystem stability.
Why keystone species are so important to ecosystem function?
The keystone species is critical to maintaining the stability of an ecosystem, and changes in its population indicate changes in ecosystem health.
Is extinction bad for the ecosystem?
Yes, extinction can be detrimental to ecosystems as it disrupts the balance of species interactions and can lead to cascading effects throughout the food web. When a species goes extinct, it can alter the availability of resources, affect predator-prey relationships, and reduce biodiversity, which is crucial for ecosystem resilience. The loss of a single species can also diminish the ecosystem's ability to adapt to changes, ultimately threatening the stability and health of the environment.

What is the role of an apex predator in the trophic level of an ecosystem?
An apex predator plays a crucial role in maintaining the balance of an ecosystem by controlling the population of other species in the food chain. They help regulate the number of prey species, which in turn affects the entire ecosystem's health and stability.
How does the introduction of invasive species such as the brown tree snake upset the stability of an ecosystem?
The introduction of invasive species like the brown tree snake can disrupt ecosystem stability by preying on native species, leading to population declines or extinctions. This predation can alter food webs and resource availability, affecting other organisms that rely on the prey for survival. Additionally, invasive species often compete with native species for resources, further destabilizing the ecosystem and reducing biodiversity. Ultimately, these changes can have cascading effects, impacting ecosystem functions and services.

Typically, the species that it ate overpopulate, and the ecosystem is disrupted.
What is the predator definition in biology and how does it relate to the ecological interactions within an ecosystem?
In biology, a predator is an organism that hunts and feeds on other organisms, known as prey. Predators play a crucial role in maintaining the balance of an ecosystem by controlling the population of prey species. This relationship, known as predation, helps regulate the abundance of different species within an ecosystem and can impact the overall biodiversity and stability of the ecosystem.
What consequences does altering a food web have on an ecosystem?
Altering a food web can lead to significant disruptions in an ecosystem, as it affects the balance of predator-prey relationships and resource availability. This can result in population declines or overpopulation of certain species, leading to further imbalances. Additionally, the loss or introduction of species can impact nutrient cycling and habitat stability, ultimately affecting biodiversity and ecosystem resilience. Such changes can trigger a cascade of effects, compromising the health and functionality of the entire ecosystem.
What is the significance of the predator animal in the ecosystem and how does it impact the balance of nature?
Predator animals play a crucial role in maintaining the balance of nature within an ecosystem. They help regulate the population of prey species, preventing overpopulation and ensuring the health of the ecosystem. By controlling the population of prey animals, predators also help maintain biodiversity and promote the overall stability of the ecosystem.
Can you explain the predator-prey relationship and how it impacts the ecosystem?
The predator-prey relationship is a dynamic where one organism hunts and consumes another for food. This interaction helps regulate the population of both species, maintaining balance in the ecosystem. Predators control the population of prey species, preventing overpopulation, while prey provide a food source for predators. This relationship is crucial for the health and stability of ecosystems.

Removing a species can also have cascading effects, such as disrupting predator-prey relationships or altering nutrient cycling processes. Both scenarios can result in changes to biodiversity and overall ecosystem stability.
What is Predator mediated coexistence?
Predator-mediated coexistence is when the presence of a predator in an ecosystem helps promote coexistence among various species by controlling the population size of dominant competitors. Essentially, the predator prevents one species from outcompeting and eliminating others, thereby maintaining a balance in the ecosystem.
Why keystone species are so important to ecosystem function?
The keystone species is critical to maintaining the stability of an ecosystem, and changes in its population indicate changes in ecosystem health.
What is the significance of the black spider with brown on its back in the ecosystem?
The black spider with brown on its back plays a significant role in the ecosystem as a predator that helps control insect populations. By preying on insects, the spider helps maintain balance in the ecosystem and prevent overpopulation of certain insect species. This contributes to the overall health and stability of the ecosystem.
