What are some ecological interrelationships in rainforests?

Question

I have been searching for the answer for half and hour but haven't got anyhing. PLEASE HELP!!! please, please?

Answer 1

1.  Rainforests are responsible for converting approximately 20% of the world's carbon dioxide (CO2 - the greenhouse gas of primary concern to global climate change scientists) back into oxygen.  

2. Deep tree root systems prevent soil erosion, especially on sloped land.  When trees are removed, soil and its nutrients easily erode.  This is particularly important when it comes to lakes and other water bodies.  When too many soil nutrients (particularly phosphorus and nitrogen) find their way into lakes, aquatic plant growth (like algae) is increased.  This, in turn, decreases the amount of dissolved oxygen in the water and can cause fish kills, toxic algal blooms, and overall reduced water quality.  This process is known as eutrophication.

3. Brazil nut trees (Bertholletia excelsa) are dependent on several animal species for their survival. These large canopy trees found in the Amazon rainforest rely on the agouti, a ground-dwelling rodent, for a key part of their life cycle. The agouti is the only animal with teeth strong enough to open their grapefruit-sized seed pods. While the agouti eats some of the Brazil nut's seeds, it also scatters the seeds across the forest by burying caches far away from the parent tree. These seeds then germinate and form the next generation of trees. For pollination, Brazil nut trees are dependent on Euglossine orchid bees. Without these large-bodied bees, Brazil nut reproduction is not possible. For this reason, there has been little success growing Brazil nut trees in plantations—they only appear to grow in primary rainforest.

4. Capuchin monkeys lap nectar from flowers in trees as part of their varied diet.  In the process they get pollen on their faces and pollinate the flowers.

5.  Do a search for: symbiotic relationships rainforest

Answer 2

it rains. trees collect some water send it up to the leaves, some evaporates, rains somewhere else. or all kinds of things eat each other in some form of interrelationship.
