Environment
What is the definition of "environment"?
The surroundings or conditions in which a person, animal, or plant lives or operates.
What is an ecosystem?
An ecosystem is a community of living organisms interacting with one another and their physical environment.
Define competition in an ecosystem.
Competition occurs when two or more organisms vie for the same resources (food, space).
How does human activity affect food chains?
Human activities, like overfishing or pollution, can disrupt food chains by removing key species or introducing toxins.
Define "habitat".
A habitat is the natural home or environment of an organism.
List three examples of different environments
Forest, desert, ocean.
Name two types of ecosystems?
Rainforest, coral reef.
What is a predator-prey relationship?
A predator-prey relationship is where one organism (predator) hunts and eats another (prey).
Give an example of a contemporary issue that involves science and technology.
Climate change, renewable energy solutions, or pollution control.
What are the levels in an ecosystem?
Levels in an ecosystem include producers, consumers, and decomposers.
How do human activities impact the environment?
Pollution, deforestation, climate change.
Identify three factors that make up an ecosystem.
Biotic factors (living organisms), abiotic factors (non-living elements), and energy sources (like sunlight).
Explain what parasitism is and give an example.
Parasitism is a relationship where one organism benefits at the expense of another (e.g., ticks on mammals).
How might solutions to environmental problems impact society?
Solutions can lead to job creation, changes in lifestyle, or economic impacts on certain industries.
Identify and give examples of abiotic factors.
Examples of abiotic factors: sunlight, water, soil, air.
Describe how scientific knowledge has changed our understanding of the environment?
Scientific knowledge has evolved through research, leading to better understanding and conservation efforts.
Explain the difference between biotic and abiotic factors.
Biotic factors are living components (plants, animals), while abiotic factors are non-living (water, soil, temperature).
Describe mutualism and provide an example from nature.
Mutualism is a symbiotic relationship where both organisms benefit (e.g., bees pollinating flowers).
Discuss the role of scientific evidence in shaping public policy.
Scientific evidence guides lawmakers in creating regulations that protect the environment based on current research.
List examples of biotic factors.
Examples of biotic factors: plants, animals, fungi, bacteria.
What ethical considerations are involved in environmental science?
Ethical considerations can include the impact of human actions on wildlife, sustainability, and environmental justice.
Describe how ecosystems can be affected by human activity.
Human activities such as pollution, habitat destruction, and resource extraction can disrupt ecosystems.
What is commensalism? Provide an example of this interaction.
Commensalism is a relationship where one organism benefits while the other is neither helped nor harmed (e.g., barnacles on whales).
Why is it important to consider ethical implications in scientific research?
Ethical implications include considering the long-term effects of actions on ecosystems and future generations.
Explain how organisms interact within ecosystems.
Organisms interact in various ways such as competition, predation, and symbiosis, affecting their survival and population dynamics.
