Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organisms and waste, returning nutrients to the soil, which is essential for nutrient cycling.

Front

How does climate change impact ecosystems?

Back

Climate change can lead to the extinction of species by altering habitats and affecting food availability.

Front

What processes provide energy for life?

Back

Photosynthesis and cellular respiration are the primary processes that provide energy for life processes.

Front

What is NOT a negative effect of human activities on the environment?

Back

Speciation is NOT a negative effect; it refers to the formation of new and distinct species.

Front

How do invasive species threaten biodiversity?

Back

Invasive species threaten biodiversity by competing with native species for resources, which can lead to declines in native populations.

Front

Define biodiversity.

Back

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

Front

What is habitat destruction?

Back

Habitat destruction is the process by which natural habitat becomes incapable of supporting its native species, often due to human activities.

Front

Explain the concept of an ecosystem.

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic components.

Front

What is the significance of photosynthesis?

Back

Photosynthesis is crucial as it converts solar energy into chemical energy, producing oxygen and organic compounds that sustain life.

Front

What are the effects of pollution on ecosystems?

Back

Pollution can harm organisms, disrupt food chains, and degrade habitats, leading to loss of biodiversity.
