What is one effect of habitat loss on organisms?

Habitat loss significantly impacts organisms primarily by leading to a loss of food sources and shelter. When natural habitats are destroyed or altered—due to activities like deforestation, urbanization, or agriculture—the native species that rely on these environments for survival face immediate threats. Without their natural habitats, organisms may find it challenging to locate food, which can lead to malnutrition or starvation. Additionally, the destruction of these habitats removes essential shelter, exposing organisms to predators, harsh weather conditions, and other dangers, further endangering their survival.

In contrast, options such as increased population density, decreased competition among species, and improved reproductive success do not accurately reflect the consequences of habitat loss. Habitat destruction usually results in reduced space and resources, so we see an increase in competition rather than a decrease. With less room and fewer resources, organisms are more likely to struggle with overcrowding, which can negatively affect their health and reproduction.
