Which of the following is an example of a human activity that can result in changes in ecosystems?

How can evidence be used to support the claim that changes in ecosystems have resulted from human activities?

What is one potential consequence for an ecosystem's biodiversity as a result of pollution?

Human Activities and Ecosystems

Urbanization leads to habitat destruction, altering local ecosystems and disrupting species.
Agriculture changes land use, impacting soil quality and water systems.
Resource extraction, such as mining and logging, depletes natural habitats and resources.

Consequences of Deforestation

Loss of habitat reduces species diversity, potentially leading to extinction of some species.
Alteration of local climate and soil composition can affect remaining flora and fauna.
Disruption of water cycles, resulting in increased flooding and reduced water quality.

Data Analysis in Biodiversity Prediction

Statistical models can assess relationships between environmental changes and biodiversity loss.
Historical data provides insights into trends, helping to forecast future ecosystem responses.
Geographic Information Systems (GIS) can visualize habitat changes and species distributions over time.

Evidence Supporting Human Impact on Ecosystems

Longitudinal studies show correlations between industrial activity and biodiversity declines.
Fossil records indicate past extinctions coinciding with human development periods.
Remote sensing technology reveals changes in land use patterns linked to human expansion.

Consequences of Pollution on Biodiversity

Persistent chemicals can accumulate in food chains, harming wildlife populations.
Altered water quality due to runoff can lead to algal blooms, suffocating aquatic life.
Air pollution affects plant health, disrupting ecosystems and threatening species that rely on affected flora.

This quiz focuses on the impact of human activities on ecosystems and biodiversity. It explores the use of evidence to support claims, predicts potential consequences for biodiversity resulting from human activities, and analyzes data to make predictions about the effects on biodiversity in response to environmental changes.
