Question

how does the edge effect impact natural ecosystems? it decreases the pressure on natural species. it makes it easier for species to find food, water, and shelter. it changes the natural environmental conditions resulting in more pressure on natural species.

Explanation:

The edge effect in ecology refers to changes in environmental conditions at the boundary of two ecosystems. This often leads to altered habitats, which can increase competition, predation, or other stressors for species, thus putting more pressure on them. The first option is incorrect as edge effect typically increases, not decreases, pressure. The second option is incorrect because edge habitats are often more fragmented and less stable, making it harder for species to find resources. The third option correctly describes that edge effect modifies environmental conditions (like light, temperature, species composition) leading to increased pressure on natural species.

Answer:

It changes the natural environmental conditions resulting in more pressure on natural species.
