Biology

unit 1 test

Habitat

the natural environment where a plant of animal lives or grows

Niche

The roles and interactions that organism have

Predation

one organism hunting and consuming another organism

predator vs. prey

Parasitism

one organism benefiting and the other having negative effects

(tick on a deer)

Mutualistic Relationships

two species that interact in a way that benefits both in the relationship

(bird eating tick off of a rhino’s back)

Population Growth and Limiting Factors

How fast a population grows and what makes it slow down or sped up

(little food, predators, little to no mates, diseases, natural disasters)

why do Ecosystem change

sudden disturbances (natural disasters) and how they reshape the populations and communities

Population distribution

distribution patterns, including clumped distributions influenced by resource availability and competition for space, as well as uniform and random distributions

what is ecology

the study of relationships b/w living organism

density-dependent factors

play a crucial role in population regulation

Range tracking devices

devices that study the population's ecology (the study of relationships b/w living organism)

Carrying capacity

not a fixed number, changes due to different factors. Gain information why carrying capacities change

Biodiversity

Variety of all things in an ecosystem

Keystone species

organism that has a disproportionately large effect an ecosystem

Beaver building a damn

trophic levels

Symbiotic relationships

commensalism, mutualism, and parasitism.

Ecological succession

gradual process where a community changes

Biotic

living

abiotic

non-living

Anthropocene Effect

Human having impacted geology and ecosystems

limiting factors

factors that can retrain population

( there is not enough food the population will go down)

levels of Ecological Organization

Survivorship curves

the life span and growth of a species in a graph

food web

how energy cycles through ecosystems in the form of food

energy flow

how the energy gets pasted along in the food web
