Limiting factors are preventing further population growth.

Front

What is the definition of an ecosystem?

Back

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

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food web.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem, while abiotic factors are non-living components, such as water, soil, and climate.

Front

What is the significance of biodiversity in an ecosystem?

Back

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

Front

What are limiting factors in population growth?

Back

Limiting factors are environmental conditions that restrict population growth, such as food availability, predation, and disease.
