Factors affecting populations in ecosystems

Front

What is desalination and why is it used?

Back

Desalination is the process of removing salt from seawater to make it suitable for irrigation and drinking. It is used to address the increasing demand for freshwater as natural sources become scarce.

Front

What is a potential environmental impact of desalination on marine ecosystems?

Back

Desalination can alter ocean salt levels, leading to loss of species and unbalanced populations in marine food webs.

How does the decline of shark populations affect ocean biodiversity?

Back

The decline of sharks disrupts the entire food chain in the ocean, leading to imbalances in marine biodiversity.

Front

What are biotic factors?

Back

Biotic factors are living components of an ecosystem that can affect the population and distribution of organisms, such as competition, predation, and availability of mates.

Front

Give an example of a biotic factor affecting a population.

Back

An example is a squirrel that cannot find a mate, which directly affects its ability to reproduce and maintain its population.

Front

What is the difference between biotic and abiotic factors?

Back

Biotic factors are the living elements of an ecosystem, while abiotic factors are the non-living physical and chemical components, such as temperature, water, and soil.

Front

What role do predators play in an ecosystem?

Back

Predators help maintain the balance of populations within an ecosystem by controlling the numbers of prey species.

Front

What is species distribution?

Back

Species distribution refers to how populations of a species are spread out across a given area, influenced by both biotic and abiotic factors.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to ecosystem resilience, stability, and productivity, allowing ecosystems to better withstand environmental changes.

Front

How can human activities impact species distribution?

Back

Human activities such as urbanization, pollution, and climate change can alter habitats and resources, affecting where species can live and thrive.
