What are abiotic factors?

Back

Abiotic factors are the non-living components of an ecosystem, such as sunlight, water, temperature, and soil.

What is a niche?

Back

A niche is the unique role or function of a species within its ecosystem, including how it obtains resources and interacts with other organisms.

Front

What is an invasive species?

Back

An invasive species is a non-native organism that spreads widely in a new habitat, often harming native species and disrupting ecosystems.

Pollution is the introduction of harmful substances or products into the environment, affecting air, water, and land quality.

Front

What is a natural disaster?

Back

A natural disaster is a catastrophic event caused by natural processes of the Earth, such as volcanic eruptions, earthquakes, and floods.

Front

What is the impact of deforestation on ecosystems?

Back

Deforestation leads to habitat loss, decreased biodiversity, and disruption of the water cycle, negatively affecting ecosystems.

Front

What is the relationship between biotic and abiotic factors?

Back

Biotic and abiotic factors depend on each other; for example, plants (biotic) need sunlight and water (abiotic) to grow.

Front

What is the role of decomposers in an ecosystem?

Back

Decomposers break down dead organic matter, recycling nutrients back into the soil and supporting plant growth.
