Biology-Ecology

Ecology

the study of the interactions between organisms and their environment

lithosphere

outermost layer of earths crust; dirt,soil

Atmosphere

Air

Hydrosphere

water

Biotic factors

all living organisms that impact an enviroment

abiotic

non-living parts of an organism’s environment

Biomes

ecological areas classified on their climate and type of plants and animals

climate

Long-term weather conditions in the area such as temperature and rainfall.

Habitat

home of an organisms

Niche

Role and functions of organisms in their habitat/ecosystem

Biological community

Groups of different species living in the same safe space

Ecosystem

Populations of plants and animals interacting with their environment with biotic and abiotic factors

Biosphere

Portion of earth that support living things

energy source

sun main source

producers (autotrophs)

convert solar eng to chem eng through photosynthesis

consumers(heterotrophs)

herbivores,omnivores,carnivores

trophic levels

diff feeding positions in food chain or web

make their own food

producers

primary consumers(1st level consumer)

herbivores that eat producers

secondary consumers

carnivores eat herbivores

tertiary consumer(3rd level)

eat other carnivores

quaternary consumer(4th level)

apex predator

energy level in trophic levels

10% of energy is passed to next level, each level loose energy thru heat

two limiting factor types

dependent,independent

dependent limiting factor

impactful only on high popul density; ex disease,competition,predation

independent limiting factor

impactful no matter popul density;ex natural disaster,temp,pollution
