an organized system that requires a constant input of energy to maintain itself.

Tree of Life is based on

True Plants

11

Solanum lycopersicum, is a single species of plant, originally from the Andes

The tomato

12

Robert Marquis and Chris Whelan studied the role of birds in limiting the density of herbivorous insects.

Ecological Hypothesis Test

13

The ecological time scale is shorter than the evolutionary time scale, but there is some overlap-populations evolve over time, and this can affect the composition of communities and functioning of ecosystems.

True

14

As young, clear channel catfish much more susceptible to predation in streams with clear water, and turbid, cloudy streams facilitate survival.
Adults are strong swimmers.
Thus, channel catfish populations extend along major rivers in Illinois.

Channel catfish prefer fast-moving, gravel-bottomed rivers of medium to large size

15

For most organisms, life histories have evolved to maximize an organism’s expected...

fitness

16

Pacific salmon hatch in the headwaters of streams and migrate to the open ocean. They eventually return to freshwater streams to reproduce.

Life history is adapted to its environment

17

are genetic variants of the same species (salmon) that stay in estuaries rather than migrating to the open ocean.

Steelhead trout

18

Each morph exploits a life history where it avoids competition with the other morph

polymorphic

19

passerines and parrots. Young are born blind and require constant parental care, after a period of egg incubation.
