5.1 Ecosystem Stability

Front

What is an invasive species?

Back

A species that is not native to an area and can cause harm to the environment, economy, or human health.

Front

What are the main ways humans cause extinction?

Back

By overhunting animals for food or products, destroying natural habitats, and polluting environments.

Front

What is a biodiverse ecosystem?

Back

An ecosystem with a variety of species that can withstand changes in resources and recover quickly from disasters.

Front

Why are invasive species problematic in new ecosystems?

Back

The new ecosystem isn’t adapted to their presence, which can disrupt local species and ecological balance.

Front

How does deforestation impact ecosystems?

Back

It can lead to a decrease in populations of insects and birds due to loss of habitat.

Front

What is ecosystem stability?

Back

The ability of an ecosystem to maintain its structure and function over time despite disturbances.

Front

What role do native species play in an ecosystem?

Back

They are species that have evolved in a specific area and contribute to the local ecological balance.

Front

What is the impact of pollution on ecosystems?

Back

Pollution can harm species, disrupt food chains, and degrade habitat quality.

Front

How does biodiversity contribute to ecosystem resilience?

Back

Higher biodiversity allows ecosystems to better withstand and recover from environmental changes and disasters.

Front

What is habitat destruction?

Back

The process of altering or eliminating natural environments, often due to human activities, leading to loss of species.
