Habitat destruction contributes the most in the loss of biodiversity these days.

More and more space is required to fulfill the demands of increasing human population.

More and more natural habitats are being destroyed for building houses, agriculture, building dams, roads, pipes, industries et cetera.

Lelu [443]

Answer:

It causes oxygen depletion in the water

Explanation:

When the amounts of organic matter in the water are significant, the activity of aerobic bacteria and other decomposers increases.  

Organic matter suffers decomposition in the presence of oxygen. Microorganisms degrade it while consuming dissolved oxygen in the process. Bacteria show fast and exponential growth, so the more organic matter, the more aerobic bacteria, and the less available oxygen in the water.

Organisms that usually inhabit these waters are affected by the lack of oxygen. Plants, algae, animals, and other invertebrates that need it to survive, find themselves limited in these environmental conditions. Eventually, they dye and contribute with more organic matter.

Little by little, sedimentation begins caused by the death of vegetables and animals, sinking in the bottom.

When oxygen disappears, anaerobic bacteria grow and act, producing fermentation.
