Question

Habitat loss and fragmentation, over exploitation, alien species invasion and co-extinction are causes for:

• A. Population explosion
• B. Competition
• C. Biodiversity loss
• D. Natality

Answer 1

The Correct Option is C

The question concerns the causes of a particular ecological issue, with options provided. Analyzing the factors given—habitat loss and fragmentation, over-exploitation, alien species invasion, and co-extinction—helps identify the phenomenon they affect:

1. Habitat Loss and Fragmentation: This refers to the destruction and subdivision of habitats, leading to reduced biodiversity as species lose their natural environments.
2. Over-exploitation: This involves excessive use of natural resources, causing population declines and extinction of species, further reducing biodiversity.
3. Alien Species Invasion: Non-native species can outcompete, predate, or bring diseases to native species, disrupting ecosystems and diminishing biodiversity.
4. Co-extinction: The extinction of one species can lead to the extinction of others that depend on it, further decreasing biodiversity.

Each of these factors directly contributes to Biodiversity loss, as they lead to the decline or extinction of species and the degradation of ecosystems, reducing the variety of life forms on Earth. Therefore, the correct answer is

Biodiversity loss
