Standard(s):


BI 6.a-Students know biodiversity is the sum total of different kinds of organisms and is
affected by alterations of habitats.
BI 6.e-Students know a vital part of an ecosystem is the stability of its producers and
decomposers.
BI.6.f-Students know at each link in a food web some energy is stored in newly made
structures but much energy is dissipated into the environment as heat. The dissipation
may be represented in an energy pyramid.
Directions:
 Observe the diversity of life on Earth from the “Life” DVD.
 List at least 5 predators and their prey from each ecosystem in table 1.
 Research two predator-prey relationships and answer the analysis questions
below.

Analysis Questions:
1.) Copy and paste an image of your predator and prey in the boxes below.

Prey
2.) What type of biome are the predator and prey located in? Describe the
characteristics of this biome (ie climate, weather, vegetation).
3.) What other organisms does the predator you selected eat?
4.) What adaptations do both the predator and prey have that help them survive?
5.) Why must there be balance between the predators and prey in order to maintain
the stability of an ecosystem?
