Answer:
A stork eating fish with its beak = Predator/Prey
Fungi absorbing nutrients = Parasitism
Barnacles = Commensalism
Explanation:
A stork eating a fish is hunting, the stork is predator and the fish is prey.
The fungi is parasitism because it is benefiting while causing harm to its host.
The barnacles are commensalism, because they benefit from the whale but don't harm it.
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.
