Nick M., Holly B., Leah S.
WHERE IS ECOSYSTEM LOCATED?
Tropical Rainforests are located in South and Central America
Also in Africa 50 percent of rain forests are in Latin America 25 percent of Rainforests are in Asia Rainforests are also found in Southeast Asia
DESCRIBE THE ABIOTIC FACTORS OF YOUR ECOSYSTEM 12 hours of daylight 160 inches of rain each year Others may get up to 400 inches of rain The forest floor gets lots of shade
PRODUCER : BROMELIAD. HOW DOES YOUR PRODUCER RELY ON OTHER ORGANISMS IN THE TROPICAL RAINFOREST TO SURVIVE?
Pools form around the bromeliad and frogs lay their eggs in them
Tadpoles give nutrients to the bromeliad from their droppings
Bromeliads are attached to trees to grow
HOW DO OTHER ORGANISMS OF YOUR ECOSYSTEM RELY ON YOUR PRODUCER TO SURVIVE? Pools form around the bromeliad and frogs
lay their eggs in them Frogs, snails, flatworms, tiny crabs, and
salamanders spend their whole lives in the bromeliad
Bacteria attracts tiny crustaceans which attract the bigger insects
HOW DO HUMANS AFFECT YOUR ECOSYSTEM? People work with government to educate
people to save rainforests Some governments block people from
visiting certain parts of the rainforests Logging and fires destroy rainforests
CHOOSE ONE BIOTIC OR ABIOTIC FACTOR IN YOUR ECOSYSTEM & DESCRIBE HOW A CHANGE IN ONE OF THESE COULD AFFECT YOUR ECOSYSTEM.
Change: People cut down trees so there is nothing to hold the soil•Other trees can’t grow •There are no homes for the bromeliads that live on the trees•There are no homes for worms, insects, crabs, snails, frogs, and small rodents
OTHER INTERESTING FACTS:
• The rainforest houses half of the world’s estimated 5 million species
• The rosy periwinkle, a flower now in danger of vanishing from the rain forest, is an ingredient in the most effective drug for treating leukemia in children
• Strangler fig tree blocks sunlight from the highest tree until the original tree dies, thereby “strangling” it
