alina1380 [7]

Answer:

We are in Tropical Rainforests.

Explanation:

Biome is basically an ecological region of earth that has specific type of flora and fauna (plants and animals). Every biome has specific abiotic factors like specific climate, temperature, geology, vegetation, soils and relief.

There are total 8 biomes in the world

  • Desert
  • Grassland
  • Temperate Boreal Forest  
  • Chaparral
  • Tropical Savanna
  • Tropical Rainforest
  • Tundra
  • Temperate Deciduous Forest

Now in our question, we have been given some conditions and are asked to identify the biome. The annual precipitation is about 300 cm and the average temperature is around 25 degrees Celsius.

Now, if we study the characteristics of all these biomes, it is very simple to identify that the biome is Tropical Rainforest.

Important characteristics of Tropical Rainforest:

  • They receive more than 200 cm of rain each year.
  • The temperature of the biome is between 20 degree Celsius and 25 degree Celsius during the whole year.
  • Around 50 percent of the animal specie of the world are found here.

<em>Note: </em><em>You can study the characteristics of world’s other biomes in the link : http://www.physicalgeography.net/fundamentals/9k.html </em>


Hope it helps!  :)

The product of the beta decay of the nuclides shown in the question is described in the image attached to this answer.

The lifetime of a human is approximately 71 years. Which of the following is this number closest to? Remember the following conv
jarptica [38.1K]

2.2Giga

Explanation:

Given that the number of years = 71years

We need to convert this to seconds;

   60s = 1 min

    60 min = 1hr

   24hr = 1 day

   7 days = 1 week

    52 weeks = 1yr

 71 years x \frac{52weeks }{1yr}  x \frac{7 days}{1 week } x \frac{24hr}{ 1day }  x \frac{60min}{1hr} x \frac{60s}{1min}  = 2,232,921,600‬s

This value is 2.2 x 10⁹s  = 2.2Giga
