Community Ecology
A(n) ____ is a group of populations/species found in the same geographic space at the same time.
Community
These types of interactions between two different individuals within the same species.
A long-term, close association between two species in which one benefits and the other is unaffected.
Commensalism
A(n) ____ is an organism that is able to form nutritional organic substances from inorganic substances like carbon dioxide.
Autotroph
This type of energy is the energy of motion.
Kinetic
____ is the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
Biodiversity
These types of interactions occur between two individuals from different species.
Interspecific
A member of one species, predator, eats all or part of the body of a member of another species, prey.
Predation
A(n) ____ is an organism that cannot produce its own food, and gets nutrition from consuming other organism.
Heterotroph
This type of energy is present in a still object.
Potential
If this species is removed from a community, the biodiversity will diminish and the community will often collapse.
Keystone Species
If two lions compete for prey, this interaction is ____.
Intraspecific
A long-term, close association between two species in which one benefits and the other is harmed.
Parasitism
____ break down waste and deceased animals.
