Answer:
eutrophication
Explanation:
Eutrophication refers to a situation in which the aquatic environment becomes excessively enriched with nutrients. This leads to algal blooms in aquatic habitats such as lakes. These nutrients come from Fertilisers used in farming, which find their way into water bodies through run-off thereby increasing nutrient levels.
Excess nutrients causes phytoplankton to grow and reproduce at an alarming rate resulting in algal blooms. This bloom disrupts the balance in the ecosystem leading to many problems.
The algae may end up using all the oxygen in the water, causing oxygen shortage for aquatic life. Some of the algae may die, their decay may lead to further oxygen depletion. As oxygen is depleted, aquatic organisms may also begin to die.
Answer- feeling different than usual :)
Answer:
Explanation:
Two possible causes for the biggest mass extinction event in the history of our planet would be an asteroid impacting the planet and the massive volcanic activity. This mass extinction event is called the Permian-Triassic extinction. This helped many species emerge as survivors and thrive without the oppressive bigger species that died out. It hurt many species that were unable to survive the harsh conditions that resulted from everything that was happening to their habitats and food sources.
Most of the time but not always. When it doesn't, it results in a gene mutation.
