What is biodiversity?

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecological processes.

Front

Why is biodiversity important for ecosystems?

Back

Biodiversity contributes to ecosystem stability, resilience, and productivity, allowing ecosystems to better withstand environmental changes and disturbances.

Front

What factors contribute to higher biodiversity in an area?

Back

Factors include climate (temperature and rainfall), habitat diversity, availability of resources, and ecological interactions.

Front

What is an ecological niche?

Back

An ecological niche is the role or function of an organism or species within an ecosystem, including its habitat, resource use, and interactions with other organisms.

Front

How does genetic diversity affect a population?

Back

Genetic diversity increases a population's ability to adapt to environmental changes and resist diseases, enhancing its survival.

Front

What is the relationship between biodiversity and ecosystem services?

Back

Higher biodiversity enhances ecosystem services such as pollination, water purification, and nutrient cycling, which are essential for human well-being.

Front

What are some consequences of decreased biodiversity?

Back

Decreased biodiversity can lead to ecosystem instability, loss of species, reduced resilience to environmental changes, and loss of potential resources like food and medicine.

Front

How do invasive species affect biodiversity?

Back

Invasive species can outcompete native species for resources, disrupt food webs, and lead to declines in native biodiversity.

Front

What is the significance of keystone species in an ecosystem?

Back

Keystone species have a disproportionately large impact on their ecosystem, and their removal can lead to significant changes in community structure and biodiversity.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem, which supports plant growth and overall ecosystem health.
