Tropical Rainforest Amazon Rainforest, South America


  • Average of 108 inches, usually between 50 to 260 inches of rainfall per year.
  • Average temperature of 80 °F Temperature rarely gets higher than 93 °F or lower than 68 °F.
  • The Amazon has two seasons a wet and a dry season each lasting about six months.

Net Primary Productivity

Tropical rainforests are densely packed with many different plants and animals. There is a larger variety of organisms in this biome than most other places on earth. This is possible partially because of the long growing season, 365 days a year plants are able to grow. Also there is an average of 108 inches of rain per year. Tropical rain forests are usually located around the equator, mostly between the two tropics.

Soil Quality

The rain forest is packed with plants and animals. Also the growing season is all year, long this leads to very infertile soil. With so many plants growing on such a small piece of land every nutrient must be used to stay alive and grow towards the little light that penetrates the canopy. The soil depends on the recycling on an immense amount of bio mass to provide nutrients from the remaining organisms.

Invasive and Endangered


The Guava was originally introduced for its fruit. Growing and harvesting that fruit has become a large industry in many tropical countries. However the seeds are spread off of the farm land designated for the guava. It has formed dense thickets in areas that were previously occupied by other plants. This has lead it to be ranked highly in the invasive categories.

Harpy Eagle

The harpy eagle is the most powerful raptor found in all of the Americas. It is also very important to the people of Brazil, there it is known as the royal-hawk. However due to destruction of the rainforests it is decreasing in population. The harpy eagle has been almost entirely forced out of central america due to destruction of their habitat. Hunters are another threat to harpy eagles in all parts of the world. It is now found mostly in the very remote rainforest areas of Brazil.

Plants in the amazon

Banana Tree

After only one year banana trees can reach their full height, usually 10-20 feet.

Brazil Nut Tree

The brazil nut tree can reach over 160ft tall. This allows it to reach the sun light other trees cannot giving it an advantage.

Venus Fly Trap
