Rainforest Biome

By: Lydia Burns, Hailey Hudson, Brison Mann, and Conley Dellinger

  • The rainforest is full of many abiotic and biotic factors
  • Abiotic factors are things in an ecosystem that are not living
  • Biotic factors are organisms in an ecosystem that are living or were once living
  • Some biotic factors of the rainforest consist of the Africa Forest Elephant, Bengal Tiger, Chimpanzee, Common Palm Civet or Musang, Bengal Bamboo, Bougainvillea, Curare, Coconut Tree, Durian, Jambu, Kapok Tree, Mangrove Forests, Strangler Figs, Tualang
  • The rainforest has the biggest variety of abiotic and biotic factors
  • Rainforests are typically found near the equator
  • 50% of the Rainforest’s precipitation is from it’s own evaporation
  • 77 degrees Fahrenheit is the average temperature in the Rainforest
  • Some examples of abiotic factors include: climate, weather, precipitation, sunlight, and amount of water
  • The Rainforest has about 250cm of rain annually and rains more than 90 days a year
  • The Rainforests have very humid tropical climate
food webs
Food Webs

Food Webs consist of:

Producers- An organism who makes their own food by natural energy that surrounds them (sun)

Primary Consumers-An organism who eats plants

Secondary Consumers- An organism who eats Primary Consumers and other Secondary Consumers

Scavengers- An organism the eats the food left over by other organisms

Decomposers- Organism that breaks down remains of dead organisms

The sun plays a role in every food web because it provides energy to the producers

Rainforest Food Webs
  • The producers in the rainforest are plants
  • Some primary consumers in the rainforest are fungi and rodents
  • A specific example of a primary consumer in the rainforest are tapirs (a pig like animal with a long nose)
  • Secondary consumers include carnivores and omnivores
  • A specific example of a secondary consumer in the rainforest is the jaguar
  • Decomposers and Scavengers in the rainforest consist of fungi, small organisms, and bacteria
environmental changes
Environmental Changes

Environmental changes affect biotic life in the Rainforest greatly. For example droughts can cause animals in the rainforest to starve and plants to die. In 2005, the Amazon experienced a drought. This killed tons of trees in the rainforest. Also, environmental conditions cause plants and animals to adapt to their surroundings.


Symbiosis- a relationship between two animals

Commensalism- a relationship between two organisms when one benefits and the other is not affected

Mutalism- a relationship where both organisms benefit

Parasitism- a relationship is where one organism benefits and the other is harmed

rainforest symbiosis
Rainforest Symbiosis

Mutualism Relationships in the Rainforest:

Ex: Capuchin Monkeys and flowering trees

  • When the monkey is drinking nectar from the flowers it gets pollen on its face and that transfers to other tree’s flowers when they drink from another tree’s flowers

Commensalism Relationships in the Rainforest:

Ex: Ecitoninae ants and Antbirds

  • When the Ecitoninae ants carry there food they accidentally leave food behind. The Antbirds eat the left over food

Parasitism Relationships in the Rainforest:

Ex: Phorid fly and Leaf Cutter Ants

  • When the Leaf Cutter Ants are working the Phorid fly attack them and lay their eggs in the crevice of the the Leaf Cutter Ants head
