- 1NutritionIt is the process by which living organisms take in subtances to survive.
- 2What are nutrients for?Building, repairing and maintaning the body.
Getting energy to perform life processes.
Regulating body functions. - 3Types of nutrientsLiving organisms cannot use all the nutrients that exist as sources of energy for their life processes.
Organic nutrients
Inorganic nutrients - 4Organic nutrientsAre complex substances (by living organisms)
Have energetic value
ex: fats, carbohydrates and proteins - 5Taking organics nutrients.Not all living organisms take organic nutrients from the environment.
All living organisms need organic nutrients for life.
Some living organisms produce their organic nutrients - 6Organic ClassificationHeterotrophic
Autotrophic - 7Heterotrophic organismsconsumers that cannot produce organic nutrients and they must get them from the environment.
- 8Types of heterotrophics organismsPrimary consumers: they feed on autotrophic organisms (plants). Ex: hervibores
Secondary consumers: they feed on other consumers. Ex: carnivores
Decomposers: feed on waste. Ex: fungi and bacteria. - 9Autotrophic OrganismsThey transform inorganic nutrients into organic nutrients
not energetic value => energetic value - 10Classification of autotrophic organismsPhotoautotrophs
Chemoautotrophs - 11PhotoautotrophsUse LIGHT as energy source
transform inorganic nutrients from photosynthesis intro organic nutrients - 12PhotosynthesisA chemical process in which photoautotrophics organisms produces organic nutrients using energy from the sun.
CO2 + water + light -> energy into -> O2+glucose
INORGANIC into ORGANIC
Transform light energy into chemical energy - 13ChlorophyllThe green color of autotrophs is a pigment called ...
Substances allows cells to captures energy from the sunlight
Only the plants that contain .... can perform photosynthesis - 14ChloroplastInside eukaryotic cells that contains organelles
- 15Light energyIs only used to carry out photosyntheses
- 16DigestionThe process by which heterotrophic organisms break food down into substances that cells can use
- 17Internal digestionSaliva has digestive enzimes
food is transported to the stomach
chemical digestion continues to the intestine
food is absorbed by cells living on the intestine walls - 18External digestionFungi feed of other organisms of the floor
Mushrooms variate of fungi threadlike tubes (hyphae) branch out.
Cells in fungus absorb organic nutrients
- 19Cellular respirationIt is a chemical reaction that happens inside a cell.
occurs when the organic nutrients, with oxygen obtained from the environment produces co2 and water
o2 -> energy -> co2 + h2o - 20MitochondriaCellular respiration takes place in this part of the eukaryotic cells.
It is the power station. - 21Chemical reactionsPhotosynthesis and cellular respiration are opposite chemical reactions,
In plants this two coexist. - 22Taking inorganic nutrientsLand animals
Aquatic animals
Vascular plants
Algae
Fungi
Unicellular organisms - 23Land animalsIngest water to get salts or food containing water
Take in oxygen through lungs or spiracles - 24Aquatic animalsAbsorb water and salts
Take in oxygen through gills
Small size animals absorb water, salts and oxygen through the surface of their body - 25Vascular plantsAbsorb water and mineral salts from the soil
- 26AlgaeAbsorb water through body surface
Mineral salts are dissolved on water
They need O2 and Co2 to survive - 27FungiCaptures water and minerals salts from the surface. They get oxygen from the pores and nutrients from the hyphae
- 28Unicellular organismsProtozoa and bacterias take in inorganic nutrients through cell membrane
- 29Nutrients as source of matterCells must grow and divide, this requieres matter.
Cells manufacture the biomolecules they are made of - 30Nutrients as source of energyCells use chemical energy to survive.
Organic nutrients used as fuel to get energy - 31Nutrients as regulation of functionCertain specific organic nutrients are required for regulation and coordination chemical reactions
- 32ADNNutrients mainly organic and inorganic combine to create a whole range of organic molecules of which organisms are made
- 33ExcretionThe process in which living organisms expel some substances or waste that must be released from the cell to the environment.
- 34Things in common between Autotrophic and heterotrophicCells uptake nutrients from the environment.
Using nutrients in the chemical reactions required to survive.
Releasing waste from these reactions.
