Microplastics
Invisible invaders: How microplastics silently reshape ecosystems worldwide
3 mins ago
0
What is a major challenge in addressing microplastic pollution in the environment?
Microplastics easily degrade in sunlight, so they do not accumulate significantly.
Their tiny size makes them difficult to filter and remove from ecosystems.
Microplastics only come from large plastic debris breaking down, not from manufactured products.

Organic Matter Decomposition
Microbial battles in soil dictate the fate of Earth's carbon and nutrients
5 hours ago
0
How do environmental conditions influence the rate of organic matter decomposition and its ecological consequences?
They have little effect since decomposition depends solely on the type of organic material.
Decomposition rates are constant regardless of environmental changes due to microbial resilience.
They regulate microbial activity and oxygen availability, affecting nutrient release and carbon storage.

How does coppicing contribute to the biodiversity of shaded woodlands?
By periodically opening the canopy, it allows light to reach the forest floor, supporting diverse plant and animal life.
By permanently clearing large areas of trees, it creates open habitats for wildlife.
By preventing any tree cutting, it maintains a dense, unchanging forest canopy.
