Biological changes occur based on natural selection. A species changes to best fit its environment. If an organism in a certain species is born with an effective trait (say, a tail, or more teeth, etc), then it will survive to reproduce and pass on that trait. Eventually that trait will be passed down through generations, and it becomes widespread. As the environment for a species changes (climate, food sources, etc.), the members of that species who are best fit to survive in those conditions ultimately end up being the ones that reproduce.

What events can change a climax community?
Natural disasters, such as hurricanes. It can destroy the plants as they develop.Fires can also destroy the climax community.
What is cascades events?
Cascade events refer to a series of interconnected events where one event triggers a chain reaction, leading to subsequent events. This concept is often observed in various fields, including environmental science, economics, and social sciences, where an initial change can amplify and result in broader impacts. For example, in ecology, the collapse of one species in a food chain can lead to a cascade of effects on other species and the ecosystem as a whole. Understanding cascade events is crucial for predicting outcomes and managing complex systems.
What are three things that can cause an ecosystem to change?
Three factors that can cause an ecosystem to change include climate change, which can alter temperature and precipitation patterns, affecting species distributions; human activities such as deforestation, urbanization, and pollution, which disrupt habitats and biodiversity; and natural events like wildfires, hurricanes, or invasive species introductions, which can significantly impact ecosystem dynamics and resilience. These changes can lead to shifts in species composition, loss of biodiversity, and altered ecosystem services.
How does climate change affect hurricanes?
Scientists predict that climate change will lead to "weather events" that are more frequent and more severe.
Why a species no longer exists?
A species may no longer exist due to various factors, including habitat loss, climate change, overexploitation, and invasive species that disrupt their ecosystems. Human activities, such as deforestation and pollution, can accelerate these threats. Additionally, natural events like diseases or changes in food availability can contribute to their decline. Collectively, these pressures can lead to a species' extinction when it can no longer adapt or survive in its environment.
What is The gradual change in species over time is called .?
Evolution
What might have caused mass extinctions?
Mass extinctions can be caused by a variety of factors, including volcanic activity, asteroid impacts, climate change, and changes in sea levels. These events can disrupt ecosystems and lead to widespread loss of species.
What significant events occurred at the Jurassic-Cretaceous boundary that led to the extinction of certain species?
At the Jurassic-Cretaceous boundary, significant events such as volcanic activity, climate change, and possibly asteroid impact led to the extinction of certain species, including dinosaurs. These events caused widespread environmental disruptions, leading to the decline and eventual extinction of many species.
Is Bottleneck events are always caused by the death of most of a species population?
Bottleneck events are not always caused by the death of most of a species population. Bottleneck events can be caused by man hunting a species too much, habitat destruction, or an environmental disaster.
A factor that tends to cause species to change is a?
change in environmental conditions, such as temperature, rainfall, or availability of resources. This can lead to changes in behavior, physical characteristics, or gene frequencies within a population, ultimately driving evolutionary adaptations.
According to the theory of punctuated equilibrium which event can lead to speciation?
In the theory of punctuated equilibrium, a rapid environmental change or a small isolated population can lead to speciation. This sudden change can create a new and distinct evolutionary path for a species, leading to the formation of a new species over a relatively short period of time.
