Ecosystem Changes

Front

What are biotic factors in an ecosystem?

Back

Biotic factors are the living components of an ecosystem, such as plants, animals, and microorganisms.

Front

What are abiotic factors in an ecosystem?

Back

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

Front

How do changes in an ecosystem affect biotic and abiotic factors?

Back

Changes in an ecosystem can impact both biotic and abiotic factors, leading to shifts in species populations, habitat conditions, and overall ecosystem health.

Front

Can changes in an ecosystem be caused by humans?

Back

Yes, human activities such as pollution, deforestation, and urban development can cause significant changes in ecosystems.

Front

Can changes in an ecosystem be caused by natural events?

Back

Yes, natural events like wildfires, floods, and volcanic eruptions can lead to changes in ecosystems.

Front

What is a short-term change in an ecosystem?

Back

A short-term change is a temporary alteration in the ecosystem, such as a flood that affects the population of a species for a limited time.

Front

What is a long-term change in an ecosystem?

Back

A long-term change is a permanent or prolonged alteration in the ecosystem, such as climate change affecting species over decades.

Front

Give an example of a natural change to an ecosystem.

Back

A volcanic eruption is an example of a natural change that can drastically alter the landscape and ecosystem.

Front

What happens to energy in an ecosystem after a forest fire?

Back

After a forest fire, much of the energy stored in organisms is released as heat, and the remaining energy in surviving organisms is limited.

Front

What is the role of plants in an ecosystem after a disturbance like a fire?

Back

Plants begin to photosynthesize again, converting sunlight into energy, which helps restore the ecosystem.
