Question

part 3: short answer - critical thinking
instructions: answer the following questions in 3 - 5 sentences each. use real - world examples to support your answers.

1. how does habitat fragmentation affect animal populations over time?
2. what are some human activities that lead to habitat degradation, and how can we reduce their impact?
3. why is habitat destruction considered the most severe form of habitat loss? how does it differ from fragmentation and degradation?

Explanation:

1. Habitat fragmentation divides large habitats into smaller, isolated patches. For example, building roads through forests. This restricts animal movement, gene - flow, and access to resources, harming populations over time.
2. Deforestation for agriculture and urbanization are major human activities causing habitat degradation. Planting trees and sustainable land - use can reduce the impact.
3. Habitat destruction is the complete loss of a habitat, like when a wetland is filled for development. Fragmentation and degradation are partial losses. Fragmentation creates barriers, while degradation reduces habitat quality.

Answer:

1. Habitat fragmentation divides habitats into smaller patches, restricting animal movement and gene - flow, e.g., roads through forests harm populations over time.
2. Deforestation for agriculture and urbanization lead to habitat degradation. Planting trees and sustainable land - use can mitigate the impact.
3. Habitat destruction is total habitat loss (e.g., wetland filling), while fragmentation and degradation are partial losses with different impacts on habitats.
