Answer:
1.When the ecological balance is favorable, it ensures that each organism multiplies and live as expected. Every living organism gets proper food which keeps them alive. A maintained balance of nature is also necessary as it leads to the continued existence of the organisms
2.The most obvious result of the removal of the top predators in an ecosystem is a population explosion in the prey species. ... When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other. When the predators are removed, prey populations explode.
3.If overfishing continues, more species will be driven to extinction and aquatic ecosystems will collapse. Fisheries should behave responsibly because they are major forces of ecological and evolutionary change.
4.The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans. The negative effects on health and the environment caused by algal blooms hurt local fishing and tourism industries.
5.It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.
