Identify the cost or costs of hydroelectric power plants: Water at the bottom of the reservoir lake (behind the dame contains colder water with less oxygen than surface water. When this is released into the rive downstream, it ca affect the fish living these that are accustomed to warmer, oxygen-rich water.

Dams without side channels interfere with fish needing to swim upstream to lay eggs for reproduction may not be able to get past the dams and young fish that are swimming downstream may be killed by the turbine blades. This has caused a severe decrease in sockeye salmon populations in areas of Northwest U. S.

All of these are some of the possible costs of hydroelectric power plants.

Sometimes a lot of water is released by a dam at a given time, resulting in flooding downstream. This affects both wildlife and drinking water. Flooding also often occurs during the construction of a dam as the reservoir fills in areas that were once above the water level forcing people and animals to relocate due to lost habitat.

please help quickly its overdue :(

The total installed costs for the majority of hydropower projects commissioned between 2010 and 2019, range from a low of around USD 600/kW to a high of around USD 4 500/kW. However, given the highly site-specific nature of hydropower it is not unusual to find projects costs outside this range.

Explanation:

The correct answer is

Hope this helps!

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
