Common Assessment 3 Environmental Science

Front

What is a feedback loop in an ecosystem?

Back

A feedback loop is a process in which the output of a system influences its own operation, promoting stability and self-correction in response to changes.

Front

What role do natural disturbances play in ecosystems?

Back

Natural disturbances, such as fires or hurricanes, can lead to ecological succession, which is the process of change in the species structure of an ecological community over time.

Front

What is ecological succession?

Back

Ecological succession is the gradual process by which ecosystems change and develop over time, often following a disturbance.

Front

What is an invasive species?

Back

An invasive species is a non-native species that spreads widely in a new habitat and can cause harm to the environment, economy, or human health.

Front

How can the introduction of an invasive species affect native species?

Back

The introduction of an invasive species can lead to the extinction of native species by outcompeting them for resources.

Front

What is 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 is the significance of native plants in an ecosystem?

Back

Native plants are important for maintaining the local ecosystem's health, providing habitat and food for native wildlife.

Front

What is a dichotomous key?

Back

A dichotomous key is a tool that allows the identification of organisms based on a series of choices that lead the user to the correct name of a given item.

Front

What is the impact of feedback loops on ecosystem restoration?

Back

Feedback loops contribute to ecosystem restoration by promoting stability and self-correction in response to environmental changes.

Front

What is the difference between parasitism and commensalism?

Back

Parasitism is a relationship where one organism benefits at the expense of another, while commensalism is a relationship where one organism benefits and the other is neither helped nor harmed.
