Front

What are limiting factors in an ecosystem?

Back

Limiting factors are resources or conditions that limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem.

Front

How does overfishing affect marine ecosystems?

Back

Overfishing depletes fish populations and disrupts the marine ecosystem, leading to imbalances and potential collapse of fish stocks.

Front

What is the primary way humans impact biodiversity?

Back

Humans primarily impact biodiversity by destroying the habitats of a large number of species, leading to loss of biodiversity.

Front

What are natural resources?

Back

Natural resources are materials or substances that occur in nature and can be used for economic gain, such as water, trees, and soil.

Front

What is the main environmental issue linked to burning fossil fuels?

Back

The primary environmental issue linked to burning fossil fuels is global warming, which results from the increase of greenhouse gases in the atmosphere.

Front

Define biodiversity.

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the diversity of species, genetic variation, and ecosystem diversity.

Front

What is an ecosystem?

Back

An ecosystem is a community of living organisms interacting with their physical environment, including both biotic and abiotic components.

Front

What are renewable resources?

Back

Renewable resources are natural resources that can be replenished naturally over time, such as solar energy, wind energy, and biomass.

Front

What is habitat destruction?

Back

Habitat destruction is the process in which natural habitat is rendered unable to support the species present, leading to loss of biodiversity.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.
