What are Species
a group of organisms that have the same structure and can reproduce with one another
What is population
different species living in the same area
what is a community
populations of different species share the same area
types of diversity
- Ecosystem Diversity: different
biotic and abiotic things.
- Community Diversity: how the
different groups are different.
- Genetic Diversity: how individuals are different.

What is mutualism
benefits both organisms
what is parasitism
one benefits the other is harmed
what is commensalism
one benefits the other is neutral.
Niche
the role an organism plays in an ecosystem
adaptation
the change of an organism to fit its environment
variation
different species
natural selection
when nature selects who survives long enough to reproduce
heritable traits
traits that are passed genetically
non-heritable
traits that are learned
discrete variation
traits that are either this or that
continuous variation
traits that fall in a range
binary fission
A cell splits into two identical individuals
budding
the parent produces a small bud that detaches itself and becomes a new individual
spore production
division of cells of the parent
vegetative reproduction
uses cutting, runners, tubers, or suckers to reproduce
Sexual reproduction: parts of plant
● female part is called the pistil and consists of the stigma, style, and ovary.
● male part is called the stamen and consists of the filament and anther.
