Ecology - Living Environment Regents Questions

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead plants and animals, returning nutrients and energy back into the soil, which supports new plant growth.

Front

Back

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

Front

What are producers in an ecosystem?

Back

Producers are organisms that can make their own food through photosynthesis, such as plants and algae.

Front

What is an ecosystem?

Back

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

Front

What is the significance of energy flow in an ecosystem?

Back

Energy flow is crucial as it determines how energy is transferred from one trophic level to another, supporting life processes.

Front

What are invasive species?

Back

Invasive species are non-native organisms that spread widely in a new habitat, often causing harm to native species and ecosystems.

Front

Give an example of an invasive species and its impact.

Back

The Zebra Mussel is an invasive species that clogs pipes, harms native fish, and disrupts local ecosystems.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are living components of an ecosystem (like plants and animals), while abiotic factors are non-living components (like water and soil).

Front

What is biodiversity and why is it important?

Back

Biodiversity refers to the variety of life in an ecosystem. It is important for ecosystem resilience, stability, and providing resources.

Front

What is a food chain?

Back

A food chain is a linear sequence that shows how energy and nutrients flow from one organism to another in an ecosystem.
