Question 1

What is environmental change in the context of Biology?

Accepted Answer

Environmental change refers to any alteration in the conditions of an ecosystem or habitat. This can include changes in climate, land use, pollution levels, and the introduction of invasive species. In Biology, understanding environmental change is crucial as it affects biodiversity, species distribution, and ecosystem health.

Question 2

How does climate change impact biodiversity?

Accepted Answer

Climate change affects biodiversity by altering habitats and the availability of resources. As temperatures rise, some species may struggle to survive in their current environments, leading to shifts in species distribution. This can result in a loss of biodiversity as some species become endangered or extinct, while others may thrive and outcompete native species.

Question 3

What role do human activities play in environmental change?

Accepted Answer

Human activities significantly contribute to environmental change through deforestation, pollution, urbanization, and the burning of fossil fuels. These actions lead to habitat destruction, increased greenhouse gas emissions, and pollution, all of which can disrupt ecosystems and contribute to global environmental changes such as climate change.

Question 4

Why is it important to study environmental change in the Cambridge Lower Secondary Science curriculum?

Accepted Answer

Studying environmental change in the Cambridge Lower Secondary Science curriculum is important because it helps students understand the impact of human activities on the planet. It encourages critical thinking about sustainable practices and prepares students to make informed decisions that can help mitigate negative environmental impacts in the future.

Question 5

What are some examples of environmental changes that affect ecosystems?

Accepted Answer

Examples of environmental changes that affect ecosystems include deforestation, which leads to habitat loss; pollution, which can contaminate water and soil; climate change, which alters temperature and weather patterns; and the introduction of invasive species, which can outcompete native species for resources. Each of these changes can disrupt the balance of ecosystems and affect the organisms living within them.
