ecology

the scientific study of interactions between different organism and their surroundings

bionic

living factors that influence an ecosystem

abiotic

non-living factors tht influence an ecosystem

producers

sunlight is the main energy source for an earth

autotrophs

make their own energy

food chain

series of steps in which organisms transfer energy by eating and being eaten by

food web

network of food chain within an ecosystem

trophic levels

each step in a food chain or food web

1. producers(autotrophs)

2. primary consumers(herbivores)

3. secondary consumers(carnivores or omnivores)

4. tertiary consumers(carnivores)

ecological pyramid

diagram that shows the relative amount of energy or organism contained within each trophic level of a food chain or web

rule 10

only about 10% of the available energy within a trophic level is transferred to the next higher trophic level

competition

when two organisms of the same or different species attempt to use an ecological resource in the same place at the same time

niche

involves both the place where an organism lives and the roles that an organism has in its habitat

predatation

commensalism

one member of the association benefits and the other is neither harmed nor helped

paratism

one organism lives on or inside another organism and harms tb

biodiversity

the variety of all types of organism living in a given area

phosphorus cycle

biogeochemical; pathway by which a chemical substance moves through biotic and abiotic compartments of earth

1. weathering

2. absorption

3. decomposition

4. sediment

John Wesley Hyatt

created the first type of plastic in 1863

polymer

a chemical substance that repeats itself over and over again

three most common plastics

nylon - clothes

polycarbonate - bottle

polyvinyl chloride - in tubes and cabinets

leachate

harmful stew and its when the polyplastic combines with the material.

water cycle

a transporter for all chemicals

greenhouse effect

the process through which heat is trapped near earths surface by substances

greenhouse gasses

carbon dioxide

methane

water vapor
