Which of the following matches a human action with its impact? Construction of dam : Purification of water Use of pesticides : Contamination of drinking water Decrease in honeybee population : Increase in plant population Construction of roads : Improvement in quality of water in local lakes
OKOKOK, for the best answer here, think of each of these scenarios
How are these caused and how are these man made issues
I think its the first one
Elaborate why you think that
Construction of dam: scarcity for animals.
Because people built a dam, the impact was that they could purify the water
construction of dam : scarcity of water for animals
That's wrong, but I get where you're coming from, in areas where dams are made, it isn't to purify the water, but it's for irrigational purposes for famers
What do you think it is?
c avtually
actually
Nope
How can plants stay populated without bees
bruh
It's not like bees are killing the plants, and what bees do to plants isn't a human impact
B then?
Yes, now can you tell me why?
If i look up this question online, people say b c d is incorrect
Option B is incorrect because fertilizers reduce the population of aquatic animals. When fertilizers wash out from the soil and drain into water bodies, they increase the contribute to the increase of nutrients and chemicals which prove to be harmful to aquatic life. These nutrients, which include mainly nitrogen, help various plant lifeforms and algae to grow. This results in a drastic overgrowth in algae populations, and algae in turn produce chemicals that are toxic to aquatic animals. The overgrowth of plants and algae also demand a higher oxygen concentration, and this may result in an oxygen deficiency of it in, suffocating other aquatic animals. Option C is incorrect because honeybees play an essential role in pollinating various plants, serving to increase their population. Option D is incorrect because the construction of road often involves chemical spillages and production of harmful pollutants, exhaust fumes, tire and pavement wear, which if not taken care off, run off into nearby local lakes thereby having a bad impact on water quality.
Ahhh
But I'd have to argue with that
But maybe D is still right
Option A is correct because most animals are dependent on free-flowing rivers and freshwater for their water supply. During the building of a dam, rivers are redirected from the regions they previously supplied to the dam, which deprives the animals of what was their source of water. Dams also cause reduced quantity and flow of water in rivers, leading to scarcity of water for animals that relied on it as a source.
This is why he said option a was correct
Hmmmm
Ohhhhh, I'm sorry
Yeah that makes sense
So option A?
Yeah option A seems best now I see that explanation
Wait
But he answered a different question
I think b is right now
Which of the following matches a human action with its impact? Construction of dam : Scarcity of water for animals Use of fertilizers : Increase in the population of aquatic animals Decrease in honeybee population : Increase in plant population Construction of roads : Improvement in quality of water in local lakes
he answered this question
OHHHH
my question is different
Yeah it is
Ok ill pick b
