How does the addition of pesticides and chemicals into lakes and streams affect an ecosystem?

Social Studies

Setler [38]3 years ago

Answer:

The addition of pesticides and chemicals into the water of lakes and streams affects an ecosystem because it kills or weakens much of the fish population. Weakened fish are easy prey for predators, and predators that rely on fish for their food may find an insufficient supply. Another problem is that the water bugs or plant life that the fish feed on will increase in population, throwing off the balance of the ecosystem. Finally, algae and bacteria grow too quickly with the addition of chemical fertilizers.  This can cause dead zones, where there is not enough oxygen in the water for fish to survive.

dybincka [34]

Answer: Archetypal metaphors

Explanation:

The dominant key of archetypal metaphors are human experiences such as death, marriage, birth, and others.

Since the definition of metaphors is comparing between two or more thins, this kind of experience is compared to light, darkness, war and peace, water and the sea.

Kazeer [188]

Answer:      Grit

Explanation:   What sociologist Paul Tough felt it needed to develop in children was the courage and strength of character to work steadily and persistently toward the set goals, which is grit. Grit is therefore a positive trait that needs to be developed and that implies a strong motivation to achieve goals, so it is not a cognitive trait,  this is about stimulating curiosity, pinpointing and setting goals, and working hard to reach those goals. This trait should be developed in children at school from the earliest days, encouraging and directing children by evaluating their curiosity, directing them to social intelligence that is important when it comes to grit, for example, teaching children to be grateful for their accomplishment and help. There is an emphasis on work that, in combination with social interaction, constant improvement and shifting of criteria, means reaching the goal as well as setting new ones.
