lab 6 - abiotic factors 1

ecology

study of interactions between organisms and their environment

biotic

living components

abiotic

non-living components

Examples of biotic factors

predator, prey, living organisms (trees, flowers, plant life)

actions of biotic factors

competition for space and resources, food, or mate

Examples of abiotic factors

sunlight, temperature, soil moisture, light intensity, soil pH, weather (rainfall, hurricane, flood, natural disasters)

how can a biotic factor affect another biotic factor

seal mating between jan-march leads to increase in competition for space

how can an abiotic factor affect another abiotic factor

high sun exposure in an area leads to reduction in soil moisture

how can a biotic factor affect an abiotic factor

human use of fossil fuel and emitting CO2 leads to increase in ocean acidity

how can an abiotic factor affect a biotic factor

-the environmental temperature affects lizard behaviors

-the environmental temperature affects tiger shark distributions

north side

more moist; colder; receive sunlight but not high light intensity level

south side

more dry; warmer; intense sunlight hitting it throughout the day

abundance

number of organisms

diversity

different species of organisms (plants and animals)

scientific process

observe everyday stuff and come to conclusion; not linear; circular loop

order of scientific process

observation, question, hypothesis, experiments, data, conclusions
