Module 3: Biodiversity & Sustainability

Front

What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species, genetic diversity, and the variety of ecosystems.

Front

Why is biodiversity important for ecosystems?

Back

Biodiversity is crucial for ecosystem stability, resilience, and sustainability. It allows ecosystems to recover from disturbances and provides a wider range of resources.

Front

What does sustainability mean in the context of ecosystems?

Back

Sustainability refers to the ability of an ecosystem to maintain its functions and processes over time, ensuring that it can support diverse life forms.

Front

How do predator/prey relationships contribute to ecosystem balance?

Back

Predator/prey relationships help control population sizes, ensuring that no single species dominates the ecosystem, which maintains balance.

Front

What is genetic biodiversity?

Back

Genetic biodiversity refers to the variety of genes within a species, which contributes to the species' ability to adapt to changing environments.

Front

How does high biodiversity affect an ecosystem's resilience?

Back

High biodiversity increases an ecosystem's resilience, allowing it to better withstand and recover from environmental changes or disturbances.

Front

What is the impact of a disturbance like a hurricane on a biodiverse ecosystem?

Back

A biodiverse ecosystem is more likely to recover from disturbances like hurricanes due to the variety of species that can fulfill different roles.

Front

What is a tundra biome?

Back

A tundra biome is characterized by cold temperatures, low biodiversity, and a short growing season, often with permafrost.

Front

What is a forest biome?

Back

A forest biome is characterized by a high density of trees, diverse plant and animal life, and a more moderate climate compared to tundras.

Front

How does biodiversity relate to the survival of species during environmental changes?

Back

Higher biodiversity increases the chances of species survival during environmental changes, as there are more options for adaptation.
