Differentiate between a foundation species and a keystone
species. Give an example of each.
What is an invasive species? Give an example.
What is a pioneer species, and under what circumstances are
these species important?
Define and discuss the concept of a keystone species.
Use at least one example that is NOT the beaver, prairie dog, or
sea otter (those we went over in class). For full credit, be sure
you discuss the conservation implications of keystone species as
they pertain to “trophic cascades.”
what are the biotic interactions that occur between species? Give
and example of each biotoc interaction. How would organisms adapt
to these interactions over time (in other words what would you
expect to see in the future between these organisms)?
a)Explain how history plays a role in the distribution of
species
b)Name and describe the biotic and abiotic factors that
determines the abundance of organisms (this should be a long
answer)
c)Name and then describe the major terrestrial biomes of the
Earth, include the factors that are most important for determining
the distribution of the biomes.
What is a keystone species and how are they different from
foundation species?
What is the difference between primary and secondary succession?
Explain in detail.
How does the Biomass Accumulation Model describe succession of
ecosystems following disturbances?
keystone species- a species on which other soecies in an ecosystem
largely depend such yhat if it were removed the exosystem woukd
change drastically-> coral itself.
also need 1 heterotroph -> molluscs(ex.octopus/squid/sea
slug
this is on coral reef
Should human beings be considered a nonnative (invasive species)
or a "keystone species?" In your explanation please use at least
one example of a nonnative species to and one example of a
"keystone" species to help illustrate your point. Show why humans
do or don't act as invasive or keystone species. Use specific
behaviors and impacts in your answers. Limit your response to no
more than 500 words.
Describe trophic levels, the nature of trophic levels in
different ecosystems, and the effect of predator removal on the
structure of food webs.. Include in your answer: a. a description
of nutrient flow through terrestrial and aquatic ecosystems b. the
differences between endothermic and ectothermic ecosystems with
respect to nutrient flow and predator-to-prey ratios c. the effect
of reducing intermediate and top predators on ecosystems’
biodiversity
Describe the potential impacts of the species on humans
(positive or negative!) and include pictures. These could be
disease photos, pictures of healthy crops, waterways, etc.

be considered a keystone species in the Chesapeake Bay ecosystem.
