What is alive in the ecosystem?
Lesson 1 – Ecosystems Assessment
In South American rainforests, Goeldi’s monkeys are commonly found in the trees,
including around the Amazon. These monkeys eat fruits and berries from trees and the
trees depend on these frugivores (fruit eaters) to disperse their seeds. They also eat
mushrooms (fungi) that grow on the forest floor and breakdown the forest litter. They
are prey for hawks, ocelots, and anacondas.
Using this information, complete the following trophic cascade. Label each shape as a
decomposer, consumer, producer, and predator. Then write the different organisms
from the description above that fit into these trophic positions. Add arrows if you see
fit. You may use your worksheet to help complete this task.
