What are the two components of species diversity? (Define, too!)
1010
(1) Species richness- amount of species present
(2) Species abundance- the amount of organisms that make up each
species, aka “evenness”

Define Keystone Species.

A species that exerts strong control over a community
because of its niche

disturbance occurs.

*Secondary succession (if soil is intact after fire)
*Increased species diversity overtime.

Community 2
Herbivory- Herbivory- Coevolution occurs when a change in one species acts as a new selective force on another species, and counteradaptation of the second species in turn affects the selection of individuals in the first species.

consists of all the organisms in a community as well as the abiotic
environment with which the organisms interact.

Energy Flow
the passage of energy through the components of the ecosystem...

Why isn’t all of the energy Why isn’t all of the energy transferred from one trophic level to transferred from one trophic level to
the next? Where does it go?the next? Where does it go?

Energy is lost as heat through cellular respiration and through wastes.

*Illustrates the cumulative loss of energy with each transfer in a food chain.*Only about 10% of energy is actually passed on to each trophic level.*measured in joules or calories

*Which ecosystem *Which ecosystem provides the greatest provides the greatest
primary production for primary production for the biosphere?the biosphere?

Energy Flow*is the amount of solar energy converted to chemical energy (organic compounds) by an ecosystem’s producers for a
given area and during a give time period.

Chemical Cycling
What happens to chemicals in an ecosystem that differs from what happens to energy?

Chemical Cycling
Chemicals are recycled

Chemical Cycling
PLANTS NEED NITROGEN IN THE FORM OF NO3- (NITRATE!!)*lightning turns N2 to NO3-*Nitrogen-fixing bacteria turn N2 to NH3
and nitrifying bacteria turn NH3 into NO3-*decomposers produce NH3 when they consume deadorganisms, which will be turned into NO3- by nitrifying bacteria*wastes contain NH3, which will be turned into NO3- bynitrifying bacteria.
