describes the variety of organisms at all levels of orgaization

catalogue increased

dogs and cats

because they have many more similarities to mammals

branch of biology that describes, names, and classifies (groups) organisms according to their characteristics and evolutionary history

first grouped animals 2,400 years ago

swedish naturalist who replaced old classification system

system based on form and structure

1. domain 2. kingdom 3. phyla 4. classes 5. oders 6. family 7. genus 8. species

• Human- Homo sapien
• Amoeba- Chaos chaos
• Eastern Box Turtle- terrapene carolina triuni

study of interactions between organisms and the living and non- living components of their enviornment

foot and oxygen

release of carbon gas by cellular respiration of other animals

interconectedness

change goes up with increasing number of acorns

all of earths life; 5-6 miles above earths surface, to deepest part of oceans.

compared to thickness of an apples skin

all the nonliving environment and organisms found in a particular place

ex. pond

all the interacting organisms living in an area

ex. all fish, turtles, plants, in the pond

includes all the members of a species that live in one place at a time (just one species)

ex. flowers

place where organism lives

• living components of the enviornment
• ex. a pollinating insect

• non living factors; physical plus chemical
• ex. temperature

• has an optimal temperature range
• shown on a tolerance curve

acclimation- gold fishe raised in cold water tolerates cold water better than one raised in warm water

• regulate their internal conditions
• ex. snake

• control some of their internal conditions
• ex. bird

shade or underground

dormacy or hibernation

specific role, or way of life, of a species within its environment

• species with broad niches; can tolerate a range of conditions and use a variety of resources
• ex.apposum

• species with narron niches
• ex. koalas

• most are photosynthetic and use light
• some carry out chemosynthesis (bacteria) and use inorganic compounds

the rate at which producers in an ecosystem capture energy or sunlight

cellular respiration, maintenance and repair, making new organic material

new organic material

• rate at which biomass accumulates
• measured in (grams/m (squared)/ years)
• tropical rainforest has best net primary activity, because:
• light, temperature, precipitation

herbivore- eat producers, carnivore- eat other consumers, omnivore- eat both producers and consumers, detritovore- consumers that feed on garbage of an ecosystem, decomposer- cause decay by breakdown of complex molecules into smaller ones

• indicates organisms position in the sequence of energy transfer
• producers- level one
• herbivores- level 2
• predators- level 3

single pathway of feefing relationships among oganisms

many food chains interlinked in one ecosystem

• cougar cant break down all parts
• energy from cellular respiration cant be used
• no transfer of energy is 100 percent efficient

evaporation, transpiration, precipitation

photosynthesis, cellular respiration
