question and Solutions
Ecosystem Structure - -abiotic, biotic factors. Levels of organization, organism, species,
population, community, and ecosystem
-Abiotic Factors - -Non-living thing
Ex: Waters, soils, minerals in the soil,O2
-Biotic Fctors - -Living things
Ex: Grasses, elephants
-Levels of organization - -Primary Producers, Primary Consumers, Secondary Consumers
-Organism - -An individual living thing that can react to stimuli, reproduce, grow and
maintain homeostasis.
-Species - -A group of living organisms of similar individuals capable of exchanging genes.
-Population - -How many of one species of an organism.
Ex:Deer(how much of a deer is an organism in a population)
-Community - -Living things in an community. Groups of different species living together
in a particular place with a potential for interacting with one another.
Example:Deer
-Ecosystem - -Living and non-living things
Example: Rock, deer
-Roles in an ecosystem - -Niches- specialist vs generalist
R vs K Selected Species, Keystone species, Invasive Species, Endangered species
-Niches(Specialist vs Generalist) - -Each species occupies a niche in the community.
A niche is the role that species play and includes the type of food it eats, where it lives,
where it reproduces, and its relationships with other species.
-Generalist - -Can thrive in a wide variety of environmental conditions and can make use
of a variety of different resources. (Heterotroph)
-Specialist - -Only can range in few environments and has a limited diet.
-R Species - --Many, usually small, offspring
-Little or no parental care
-Massive deaths of offspring
-Insects, bacteria, algae, Dandelions
