What is the impact of invasive species like Lionfish on local biodiversity?

Back

Invasive species like Lionfish can decrease local biodiversity by outcompeting native species for resources.

Front

Define 'population' in the context of ecology.

Back

A population is a group of individuals of the same species that live in the same area.

Front

What is a niche in ecological terms?

Back

A niche refers to the role or function of an organism within its ecosystem, including its habitat, resource use, and interactions with other organisms.

Front

How does the introduction of non-native species, such as the Bradford Pear tree, affect native species?

Back

Non-native species can crowd out native species, decreasing their carrying capacity and overall biodiversity.

Front

What is carrying capacity in an ecological context?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can sustainably support.

Front

What are some consequences of converting natural habitats into farmland?

Back

Converting natural habitats into farmland can lead to a decrease in biodiversity and disrupt local ecosystems.

Front

Explain the term 'biodiversity'.

Back

Biodiversity refers to the variety of life in a particular habitat or ecosystem, including the number of different species and their relative abundance.

Front

What role do native species play in an ecosystem?

Back

Native species contribute to the stability and health of an ecosystem by maintaining ecological balance and supporting food webs.

Front

What is the difference between an ecosystem and a community?

Back

An ecosystem includes all living organisms in a particular area along with their physical environment, while a community consists only of the living organisms.

Front

How can human activities impact population dynamics in wildlife?

Back

Human activities such as habitat destruction, pollution, and overfishing can alter population dynamics by reducing population sizes and disrupting breeding.
