Unit 2 Apes

unit 2 apes test review

biodiversity

diversity of life forms in an ecosystem

3 levels of biodiversity

genetic, ecosystem, species

Genetic Diversity

types of genes of traits found with in individuals of a population

• high is good so its easier to repopulate/survive if some thing happens

Species Diversity

diversity of different types of organism found in a ecosystem

species richness

total number of diffrent species found in a ecosystem

species evenness

how similar the population apecies of a different species in an ecosystems are

providing services

things directly provided by nature

• trees providing wood

supporting services

processes done by ecosytems that support a valuable human action

• bees helping farmers

valuable human action

actions taken by humans that benefit society or the environment, such as sustainable farming, conservation efforts, or ecosystem restoration.

regulating services

services provided by ecosystems that help regulate environmental conditions, such as climate regulation, water purification, and pollination.

cultural services

non-material benefits people obtain from ecosystems, such as recreational, aesthetic, and spiritual experiences.

islands biography

1. islands that are closer to the main land have higher species richnesses

2. larger island habitats support more secies

islands have

higher amount of generlist species

optional range

range of an environmental condition where an organism can surve and and reproduce

zone of physicalolgical stress

range of an environmental condition where an organism can such can survive, but stress such as stunted growth or impare reproduction

periodic events

events that occur at regular intervals in an ecosystem, which can influence the conditions and dynamics of the organism populations.

• rainy season

episodic events

events that occur at irregular intervals in an ecosystem, which can have a significant impact on the conditions and dynamics of the organism populations.

• hurricane

• forest fire

primary succession

the process by which an ecosystem develops on a newly formed or exposed substrate, such as after a volcanic eruption or glacier retreat, starting from bare rock or newly formed soil.

• moss and lichen

secondary succession

the process by which an ecosystem recovers and develops after a disturbance that does not completely destroy the existing soil and biota, such as after a forest fire or flood.

• grass and seeds

keystone species

a species that has a disproportionately large effect on its environment relative to its abundance; their presence or absence significantly affects the structure and dynamics of the ecosystem.

• wolves
