vocabulary 2/27 - autotroph i can …. 2/27 – describe if a red wolf is a autotroph or heterotroph
TRANSCRIPT
VOCABULARYLiving(BIOTIC) - organisms must have all 7 characteristics of life(living and dead).
Nonliving(ABIOTIC) - things do not have all 7 characteristics.
Dead – organism once had the 7 characteristics of life but now doesn’t. It is Considered to be LIVING!!!!
ROLES IN AN ECOSYSTEM
1. Decomposer
2. Autotroph - producer
3. Heterotroph – comsumer(omnivore, herbivore, or carnivore – parasite)???
WHERE DOES A SCAVENGER FIT?
Roles in Ecosystem - YEAST1. Decomposer – break down plant material.
2. Parasite – Infect plants and animals(ringworm).
3. Animal disease
4. Lichens – Mutualistic relationship between a photsynthetic organism and a fungus. Plant makes the energy and fungus breaks down the nutrients in the environment and they share.

Multi-cellular OrganismsMulti-cellular OrganismsThe organism is made up of many The organism is made up of many cellscells
Cells have specialized functions Cells have specialized functions within the organismwithin the organism
In multi-cellular organisms, the cells specialize to perform specific functions(bone cells, skin cells, muscle cells, root cells, leaf
cells).

Eukaryotic vs. Prokaryotic
• Eukaryotic – Contains a nuclear membrane around their DNA. All kingdoms except archaebacteria and eubacteria!!!!
• Prokaryotic – No nuclear membrane – all bacteria
Reproduction is the process of producing new organisms Reproduction is the process of producing new organisms of the same typeof the same type
Asexual ReproductionAsexual ReproductionA single parent organism reproducing by itself – A single parent organism reproducing by itself – NO COMBINATION OF SPERM AND EGG!!!!NO COMBINATION OF SPERM AND EGG!!!!
Sexual ReproductionSexual ReproductionTwo different parent organisms contribute genetic Two different parent organisms contribute genetic information information
Involves the combination of male and female sex Involves the combination of male and female sex cellscells
Living organisms need Living organisms need energy to energy to grow, develop, repair damage, and grow, develop, repair damage, and reproducereproduce
Autotrophs(producers) – use the Sun’s energy to make glucose!! Produce their own food! PHOTOSYNTHESIS
TYPES OF CONSUMERS
1. HETEROTROPH – consumer
2. AUTOTROPH – producer
3. DECOMPOSER – breaks down organic material and returns to the earth.

Homeostasis• Your body maintains a constant
internal and external physical and chemical conditions. Everything is happy!! Goldilocks – Just Right!!!
Homeostasis
Dogs pant, you run a fever, sweat, or shiver, cell membranes control amount of water and waste in and out of cell, ETC
Genes carry hereditary information
Genes are composed of DNA
Heredity is the reason children resemble their parents
Mutations change DNA code and can be passed from generation to generation

ALL LIVING THINGS RESPOND TO A STIMULI
Living things respond to immediate and long-term changes in their
environment(shiver when cold, change fur color, bend toward light).
ALL LIVING THINGS GROW AND DEVELOP
To grow means to get bigger and to get bigger; more cells must be added.
To increase numbers of cells, cell division must occur.
Develop means to change into an adult(mature).
Development involves Development involves a change in the a change in the physical form or physiological make-up of physical form or physiological make-up of an organisman organism
AdaptationAdaptation
A process that A process that enables enables organisms to become better organisms to become better suited to their environmentsuited to their environment
Species obtain adaptations Species obtain adaptations through evolution over great through evolution over great periods of timeperiods of time
ALL LIVING THINGS CHANGE TO FIT THEIR
ENVIRONMENT(ADAPT)
Organisms must adapt to their changing environment or become extinct.
Adaptations occur over a very long period of time(millions of years).
Adaptation – Inherited trait that is passed from parent to offspring that helps an organism survive in its environment
An Example of AdaptationAn Example of Adaptation
Desert plants have succulent waxy leaves and Desert plants have succulent waxy leaves and stems to store water and reduce water lossstems to store water and reduce water loss
ALL LIVING THINGS HAVE DNA.
DNA provides instructions for making molecules called proteins. Proteins build cells.
DNA carries the genetic material from parent to offspring(heredity).
