An important aspect of any biological study is to communicate ideas clearly. Identify the
following statements as observations (O), hypotheses (H), or predictions (P).
_____ Tropical rain forests have high species diversity
_____ Mesquite trees have thick, dry bark to prevent water loss in the desert.
______Large-billed parrots will eat large seeds and small-billed parrots will eat small seeds.
______ Social insects will help their relatives raise offspring rather than produce their own
because they actually achieve higher indirect fitness by helping.
______ Many species of birds inhabit a single tree.
Solution
Venus fly trap :property of life : response to stimulus as the plant cannot absorb nitrogen from
soil it depends on insects for nitrogen requirement and hence has sensitive hairs that detect the
insect and close to trap the insect.
A puffin eating fish and using the energy for swimming: Energy utilization or expenditure,
organisms use the energy absorbed by them toperform various activities of life.
Roosevelt Lake. _ lake ecosystem , where different organisms and their interactions can be
studied.
One Largemouth Bass. represents an organism in the ecosystem.
