Answer 1

Answer:

1,    Tidal power or tidal energy is the form of hydropower that converts the energy obtained from tides into useful forms of power, mainly electricity. Although not yet widely used, tidal energy has potential for future electricity generation. Tides are much more predictable than the wind and the sun.

2,  A savanna or savannah is a mixed woodland grassland ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.

The tundra is located at the top of the world, near the North Pole. This enormous biome, extremely uniform in appearance, covers a fifth of the earth's surface. The most distinctive characteristic of tundra soil is its permafrost, a permanently frozen layer of ground.

3,        Tropical grasslands, savannas, and shrublands are spread over a large area of the tropics with a vegetation made up mainly of low shrubs and grasses, often including sclerophyll species.

4,       A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other. ... The moon appears new (dark) when it is directly between the Earth and the sun. The moon appears full when the Earth is between the moon and the sun.

5,   Organisms such as fungi and bacteria get energy in a different way than producers or consumers. These organisms, called decomposers, get energy by breaking down nutrients in dead organisms. ... One way to think of decomposers is as recyclers. Termites and earthworms are examples of decomposers.    

Explanation:

Answer 2

Explanation:

• 1.tidal power :
• high and low twice a day
• Hydel power
• waves are nature.
• 2.savannas:
• the grass are tall and sharp
• tundra:
• these reasons are also called the barren land.
• 3.tropical vegetation:
• the way are the same way
• deset vegetation :
• soil is the only one who can help way.
• 4.spring tide:
• such as the first time in the middle age .
• near tide:
• twice a week and I don't know what to do with the time and place.
• 5.producers :
• hence they are called autotrophs.
• decompress :
• they are all the living organisms.
