The rainforest ecosystem. Where do rainforests occur?. Why is the rainforest both an ecosystem and a biome?. A biome is An ecosystem is The rainforest is both because. What are the two main factors that affect where different biomes occur?
A biome is
An ecosystem is
The rainforest is both because
What climatic conditions do rainforests need to grow?
What is the climate of the rainforest?
What causes it to rain so much?
Which area (Africa or Europe) did we say had the sun directly overhead?
Which area has the sun spreading out over a larger area?
is hotter then?
To construct pyramids of biomass: need biomass.
To get it:
Measure mass of one organism/average of a few organisms x total of all organisms present
Biomass = total energy within a living being
So, biomass = mass of organisms – water content
(water contains no energy and is not organic)
Weigh organisms, put in hot oven, reweigh etc
2 readings the same = finish
Measured: / unit area e.g. /m2
Can do flora or fauna
Equipment: quadrat, container, oven, weighing scales.
Does a forest with four layers have more or fewer habitats than a forest with two layers?
More than 50% of the world\'s plant and animal species inhabit the 7% of the world that is covered in rainforest.A four-square mile patch of rainforest contains as many as 1500 species of flowering plants, 750 species of trees, 125 species of mammals, 400 species of birds, 100 species of reptiles, 60 species of amphibians, and 150 species of butterflies.
? is the total amount of CO2 that is fixed by the plant in photosynthesis.
? is the net amount of primary production after the costs of plant respiration are included.
Therefore,NPP = GPP ? R
Which ecosystems have the greatest gross primary productivity?
Marks animals caught
Catches animals again
To estimate population
Where do nutrients come from?
How can nutrients be lost from this system?
Is it open, closed or isolated? Why?
How is carbon transferred and transformed as it moves around the rainforest ecosystem?
How would the productivity of the forest change?

Fact: We lose 50 species everyday due to deforestation of tropical forests.Fact: Over 2,000 tropical forest plants have been identified as having anti-cancer properties.Fact: Less than 5 percent of the world\'s tropical forests are protected.
