What role does a frog play in the food pyramid?

Back

A frog is typically a secondary consumer, feeding on primary consumers like insects.

Front

What natural event can cause global cooling?

Back

Volcanic eruptions can release ash and gases into the atmosphere, leading to a temporary cooling effect on the Earth's climate.

Front

How can ice cores be used in climate studies?

Back

Ice cores contain trapped air bubbles that preserve past atmospheric conditions, allowing scientists to study historical climate changes.

Front

What is a major carbon reservoir?

Back

Living organisms, including plants and animals, are major carbon reservoirs as they store carbon in their biomass.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with each other and their physical environment.

Front

Define a food chain.

A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another.

Front

What is the difference between a producer and a consumer?

Back

Producers create their own food through photosynthesis (e.g., plants), while consumers obtain energy by eating other organisms.

Front

What is the significance of biodiversity?

Back

Biodiversity is crucial for ecosystem stability, resilience, and the provision of ecosystem services.

Front

What is a carbon sink?

Back

A carbon sink is a natural or artificial reservoir that absorbs more carbon than it releases, helping to mitigate climate change.
