succession in an ecosystem would this be an example of? - Correct Answer Primary
Ecological disturbances are: - Correct Answer change in community structure and alter resource
availability, include fires, glacial advance or retreat, and volcanic eruptions, are density independent
factors that influence species diversity and composition (all of the above)
The insect in this image is displaying: - Correct Answer cryptic camouflage
an oxpecker is a bird that usually feeds on parasites on a rhinoceros's back. it occasionally picks scabs off
the rhinoceros's back and drinks blood from the wounds. describe the relationship(s) between the
oxpecker and the rhinoceros. - Correct Answer Mutualism
For most land ecosystems (terrestrial), pyramids composed of species abundances, biomass, and energy
are similar in that they have a broad base and narrow top. The primary reason for that pattern is: -
Correct Answer at each level of production and consumption, energy is lost from the system because of
laws of thermodynamics
An ecosystem consists of: - Correct Answer a group of different species within a defined area and the
interactions within and among these species
Which of the following major nutrients CAN NOT be used directly in the form it's found in its primary
reservoir? - Correct Answer Nitrogen
Which of the following correctly describes a population? - Correct Answer individuals of different
species living in a common location
, In order to understand the structure of an ecological community which of the following would you need
for your study? - Correct Answer All of the above: figuring out how many different species are present
in the study site, determining which species are present, figuring out the kinds of interactions that occur
among organisms of specific species, determining the relative abundance of species
Researchers have found that beaver ponds in New York host over twenty species of birds, and that this
benefit to bird species lasts of decades of beaver activity. Beavers impact on community structure is an
example of: - Correct Answer Keystone species

The enzyme amylase that is present in human saliva can hydrolyze neighboring a-glucose unites. As a
result of amylase, humans can digest starch but not cellulose. This suggests that... - Correct Answer
starch is made of a-glucose monomers while cellulose is made of some other kind of glucose monomer

A potato plant grows rapidly in a sunny field in Penobscot county. How do the cells of the growing
potato (which is not exposed to light) obtain energy to do cellular work such as active transport across
the membrane? - Correct Answer Sugars are made in the leaves via photosynthesis and moved to the
root
