What are biotic factors in an ecosystem?

Back

Biotic factors are the living or once-living components of an ecosystem, including plants, animals, fungi, and microorganisms.

Front

Give an example of an abiotic factor in a desert habitat.

Back

Extreme day and night temperatures are an example of an abiotic factor that affects the living conditions in a desert habitat.

What role do pioneer species play in ecological succession?

Back

Pioneer species are the first organisms to colonize a disturbed area, initiating the process of ecological succession and helping to create conditions suitable for other species.

Front

What is the significance of biodiversity in an ecosystem?

Back

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

How does energy flow through an ecosystem?

Back

Energy flows through an ecosystem in a one-way direction, from producers (like plants) to consumers (herbivores and carnivores) and eventually to decomposers.

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and making them available for use by plants.
